Car Tech that Combats Drunk Driving

Posted August 14, 2015 5:00 AM by cheme_wordsmithy

According to the National Highway Traffic Safety Administration (NHTSA), drunk driving was involved in 31% of all fatal car crashes in 2013. Roughly 10,000 die each year in drunken-driving related accidents. Despite all the statistics, warnings, and harsh punishments for driving while impaired (DWI) and driving under the influence (DUI), every day people still make the choice to drive after drinking too much, and put themselves and others in danger. As with other safety concerns, researchers are always looking for technology's help to minimize the risk of DWIs and DUIs.

One form of technology in use today is the ignition interlock. Ignition interlocks are sometimes mandated for past DUI offenders and on rare occasions have been used voluntarily by concerned parents or others seeking driver accountability. The devices basically utilize a breathalyzer that integrates with the car's ignition. The driver must blow into the breathalyzer in order to start the car; if his blood alcohol content (BAC) is above a pre-determined level, the car will not start. The device will also request additional breaths at random times while driving to prevent the driver from deciding to drink after starting the car (if the driver is caught, the vehicle gives a warning and time to pull over before the car shuts off). BAC and operating information is monitored and can be reviewed by the judge, parent, etc. For DWIers or unruly teenagers, this device can be a good accountability tool, and in many U.S. states it is a requirement for first-time DUI offenders

While effective, ignition interlocks would not work well for the everyday driver. If you think about it, who really wants to have to blow into a tube in order to start their car? If we could remove the intrusiveness of the technology, the benefits would be worth considering. That's what the NHTSA and Automotive Coalition for Traffic Safety (ACTS) have been working on since 2008, and it's called the Driver Alcohol Detection System for Safety (DADSS). [Yes, this industry loves their acronyms... bear with me].

Like an ignition interlock, the DADSS uses sensors (in this case both breath and touch) to determine the user's BAC and regulate ignition accordingly. The difference is that DADSS does the work passively: sensors on the ignition switch would screen for alcohol on the skin's surface using infrared light, and sensors in front of the driver would measure BAC from his/her breath. These sensors are able to read and trip very quickly, so it does not inconvenience the driver in any way. And the price for the modification to new cars would be $150 to $200 currently, which is not a bad price, all things considered. On these items alone, it seems like an easy win for safety.

Unfortunately, there are many other factors that need to be considered. For instance, can we be sure the technology is reliable enough not to fail during the life of the car, or will it add to the list of possible points of failure in the vehicle? What about emergencies (confrontations, medical issues, and the like) where someone had a couple drinks beforehand but needed their car to start fast -- can we excuse those instances in the name of safety? What about the slippery slope of privacy, assuming the data can (and if it can it will) be recorded -- would we be OK if it became linked to our insurance rates, driving history, or vehicle inspections?

This is an engineering forum, and I write this post because I am intrigued by the technology that we have available today, particularly the computing power in our vehicles and the ways that capability is opening doors (albeit closing others for the traditional car enthusiasts). The DADSS is one of those doors. But as with all new tech, we must look at not just the "Can we?" but the "Should we?" and the "How?". These are the questions worth asking, ones I hope the community asks as this effort develops.

Technology is wonderful.

However, the root cause is a behavioral problem.

Like all behavioral problems legislation and technology can only be partially effective, at best. I just read about a women that crashed a car drunk after having her child breath into the ignition interlock. I suppose we could make the system respond to only that person's DNA, but then the car is only useful for one driver. Bad choice in an emergency.

There is one more problem with the nanny approach to life. This is disturbing to me because when you build a perfect nanny state of being it will completely void any need or desire for people to be self-regulating and responsible.

It's tempting to replace one's morals and scruples with more legislation and more technology, but at what cost? I suggest by doing that we are robbing ourselves of the opportunity to grow inside. There should be a balance...

However, as engineers we tend to be a little near-sighted and see the problem as a low-level one that we can proudly fix with our skill sets and walk away feeling good that we have set ourselves free from another dragon.

But have we really done that or just created a bigger dragon where good intents are just the mile markers along the road to hell?

Re: Car Tech that Combats Drunk Driving

Most of us have been in a situation where we drove a car when we were legally intoxicated (0.08 in our state); Having too much at the company's Christmas Party, a bachelor party, wedding reception, New Year's Eve Party, friend's house, at a bar, frat party in college, etc. Sometimes we think that we're okay to drive. Other times we tell ourselves that it's only a few miles away. Or that we need to get home, so even though we shouldn't be driving, we'll be extra careful. This is normal stuff in our lives and the one time when we do get caught (if we do), everything goes upside down and we learn that it isn't worth taking a chance - we never do it again.

For those with multiple DUI's, it's a psychological problem. Most times they're not just at the limit (0.08 or 0.10), but they're really drunk - stumbling drunk! For these people, they should of course get help, but also, they should lost their driving privilege forever. No mercy on them, because they're the one who's going to wind up crashing into me, my family or my friends.

As Hero points out, it's our responsibility to make sure we don't get behind the wheel when we've had too much. We make the conscious decision to drink. We make the conscious decision to turn the key and drive off. If we start with a device like this, what's next? A device to shut off your car if the CEL triggers? Or shut it off if your tire pressure is low or you haven't changed the oil when you should have?

FYI, a friend of mine in the insurance business told me that the driver's the insurance company likes the best are the ones who have a good driving record and they just got their first DUI. They pay a much higher rate, they are most likely not going to drive after even one beer and they've definitely learned their lesson.

In Wisconsin, if you are convicted of DUI (I believe the first offense) , you have to have these interlock installed at you own expense...

I had my girl friend's car in the shop, and I overheard the mechanical on the phone that told the one on the other end of the line say something to the effect $2400.00 cash up front to install one..

But then you get the woman who made US national news last week who was caught driving drunk with her 3 year old in the car. She had previously been convicted of drunk driving and did have a breath interlock in the vehicle.

She got around it by teaching the 3 year old to blow in the interlock. Nothing short of chaining them down can stop a determined drunk.

Then the government defines alcoholism as a disease and people like these aren't held accountable to the degree they should be at.

I don't know the laws where you are at, but here the laws are almost draconian.

First offense will cost you about $10,000 by the time you are through.

Florida can change a person with drunk driving if you are simply walking down the street and happen to have car keys on you and you are intoxicated.

Its at least that, I had a dated a girl that worked at a drug and alcohol center. If convicted you also have to take classes as well, Not to mention getting car insurance, and there was only on insurance outfit that would insurance convicted DUI for a very high price.

Public intoxication when walking down the street is what it's called here, there were a few people I heard of that got pinch while sleeping it off in the back seat of the car.

But it seems that after the first few offices they are convicted of, it doesn't seem to phase them. I heard on the radio that one fellow after the 9th conviction the judge really threw the book at him, but I really did find out what that meant.

So you can be charged for walking home from the bar instead of driving your car?

They should expend their resources going after people who are actually committing a crime. Laws such as these do nothing more than encourage disrespect for the law.

Or instead charge them with public intoxication,

They may have had other issues, with spring break.... Even though intoxication can be a threat,.... At times It does seem that some of these are just cash generators.

If you have car keys in your possession they can consider that as the ability to DUI.

That being said, police have discretion in how they apply the law.

I know someone who got their first DUI. They drove to a convenience store and decided that they couldn't drive, so they slept it off in the parking lot.

Police arrived and knocked on the window and determined he was still legally intoxicated. Police offered to release him to the custody of someone if they would pick him up. He called friends, but no one would answer the phone at that time of night, so he was hauled off to jail and charged with a first offense DUI. Between the attorney fees, fines, court costs, AA meetings, recurrent blood tests, etc., he was in about $10K and the loss of his license for a number of months.

At least the police tried to give him an out, but it didn't work in his case.

In Green Bay, wi. A lot of the taverns in the tavern league has free taxi/shuttle service for the patrons. I feel this is great, but I believe they had to do it.

I know that for the last 25 years, when I go out I watch my alcohol intake, and the last 10 years it's been basically next to nothing.

No one should be driving drunk, but for every drunk on the road, I suspect there are at least 10 cell phone Sallys and 10 texting Toms. I've never been run off the road by a drunk, but I have by a "phone head". Fortunately, there was a good shoulder and I could dodge the road sign.

Personally I see having a drivers licence is a privilege not a right to which effect to mean anyone who gets a DUI or similar should automatically lose their licence for 1 year with zero bargaining options available.

Second time 5 years, Third 10, Fourth 20 and no bargaining in any case Going by that rate if you get a DUI on your 18th birthday you will be 19 before you can drive again.

By the time you can get your licence back again you will likely be about 25.

Do it again and you're 35+ before you can drive again this time.

Do it one more and your 55+ and at a point where you have either outgrown the stupidity or your long life without a vehicle has brought you to a point where you likely have no need for a vehicle and licence any more.

My reasoning is that I for one am one of those people who have worked they way up to having earned a full Class A Commercial Drivers Licence with HazMat endorsements which means for me anything more than a speeding ticket every few years could affect me keeping my licence and a very large aspect of my ways of earning a rather favorable living in return.

More so in this country,... People would cry they have rights, which is true.... But these same people haven't a clue what their rights actually are. Only that they know they have rights.

While I certainly agree that drunk drivers that cause serious injury to someone should be penalized heavily, there's still the 69% of fatalities that were caused by people that weren't drunk. I find it quite upsetting how often I read about a motorcyclist run down by someone turning left that says "I didn't see him", and gets off with a relatively minor sentence. I'd prefer to see a device that would park your car if it determines that you aren't paying attention to the road, and not allow the car to be restarted for a set period of time.

Unfortunately, the motorcyclist has a smaller cross sectional area.... And the driver of the car, like the motorcyclist is human. the awareness becomes transplanted with complacency...

Also remember that at times motorcyclist put themselves at risk because of their movability.

And your suggestion is ridicules,..... take a cab.

I think society draws a line between an accident and negligence.

Making an honest good-faith effort to clear your turn and causing an accident is just that, an accident. There are penalties for that behavior.

Neglagence is not apply the due diligence or even ordinary care required to operate a motor vehicle. Loading yourself up with some chemical that impairs your ability to operate that vehicle safely, but operating anyway is more than an accident - it's criminal.

Personally, I would rather resources be applied to actually training people to drive and licensing requirements that actually amount to a test instead of a form you fill out to get behind the driver's wheel.

Then again, I have always advocated just handing out pilot's licenses to some of these people and if they attempt to fly anything like they drive it will become a self-correcting problem.

Quite a while back, in the US, when the number of motorcyclists was fewer, I saw an article about a guy that recorded the number of "I didn't see him" close encounters with his motorcycle in civilian and police bike type guise.

These encounters dropped dramatically with the police version.
