I heard about this on the radio, and it sounds like a royal goat-rope. If you have new information, please fill me in. My comments here are based solely on what I heard on the radio and have read online. I worked with GM Super cruise systems and their driver attention camera system. On a trip to Atlanta in a foreign rental car I figured out how I could exit the vehicle and have it resume driving, steering, stopping, starting, until it ran into something or ran out of fuel using just a Food Lion bag and a bungee cord to fool the system. This is the technology gap that we start with. Now we're going to add camera detection systems that detect if we're agitated, excited, or otherwise "impaired." Add to that, sensors that can detect if your blood alcohol level exceeds .08 and these sensors do this passively. Nobody is going to buy a car new car that costs $40,000 and won't start until you blow in a tube and wait twenty seconds. They are sniffing interior cabin air. So we add passive breath sensors inside the car that can detect alcohol. Can they detect if you smell like a skunk and are high as a kite? No word on that yet. But they can detect alcohol and determine if it exceeds .08 in your blood alcohol level. If it does, it won't let you start the car. Great! But wait, it gets better. Not only will it stop the car from starting, it will reduce the speed and stop the engine while you're driving down the highway if it detects alcohol. These are a few of the problems I can see with this system that will be issues. Say you're a parent of a child who has been injured. You are driving them to the emergency room. The system could detect your eye movements and aggressive driving as impairment and shut the car off. Maybe, as the designated driver, you're stone cold sober, but your passenger(s) have had a few too many. You can't even start the car. What happens when you're cruising at 80 MPH in interstate traffic, your car is in a self driving mode and without removing your eyes from the road, you open an eye glass cleaner wipe that contains alcohol? Engine stops at highway speeds? How about you're driving the kids to school on a road that's under construction. It's wet and foggy. Other cars are spraying muddy slop all over your windshield. You hit the windshield washers. The alcohol in the washer fluid is interpreted as impairment by the vehicle sensors and it cuts the engine off in the middle of a two lane bridge, in the fog. Oh, but my favorite scenario is the one where you do nothing but buy the new car. The model is recognizable enough that a whole new car jacking technique has been born just to target you I'll call it "Following in front," although the perpetrator only needs to be in front of you briefly. He could even pick a spot along a road and lay in wait for you to pass. At the crest of a hill. Spray alcohol vapor in the air. It's drawn in through your cars HVAC system and detected as impairment. The engine stops, just as you crest the hill and are out of sight to anyone else driving behind you. When you stop, you're met by a crew who "rescue" you, and while they have you occupied, they steal your key card and your car. If this sounds like some far-out science fiction stuff, consider this. In the last fifty years we have gone from military vehicles with generators (not alternators, old-fashioned DC generators), point ignitions and cable pull starters like a lawn mower, to armed drone technology. In our cars, carburetors were replaced with fuel injection, AM/FM radio has been replaced with Bluetooth, streaming and in-vehicle hot spot connections. Try to even find manual windows on a new car. You don't need to stop at a pay phone, if you can find one, to make a call. Your car has a built in phone, and voice command dialing. All you need to say is "Call Dipshit," and the number is found in your contacts on the phone in your pocket, which is linked to the vehicle, and the number is dialed. It's all so easy. There are a hundred other scenarios I can think of that would cause the impaired driver detection system, as I've heard about it, to become an issue. These are just a few. Since I don't watch TV I may be missing something about this not-so-new mandate. Feel free to share your thoughts and any new information here. Cheers
