“If steering wheels would have breathalyzers and shut the car down when it senses alchohol in the drivers breath, there would be far fewer collisions.”
An Israeli kid actually just invented something like that for teenage drivers- it’s a combination breathalyzer, webcam connected to a parent’s phone that rings him/her up when the breathalyzer shows up positive, and remote control ignition so the parent can prevent the teen from turning on the car.
