Impaired driving is also solvable. On-demand breathalyzers, smartphone saliva tests, and eye-tracking sensors are all tools that already exist to stop drunk and high drivers before they even start the ignition. Uber is already testing real-time driver sobriety verification. Why aren’t carmakers racing to put similar tech in every new vehicle?

There's no fucking way people will buy those cars is why. I rarely drink and will never buy a car that required a saliva test or blowing into a tube before starting. Like it or not, any car that includes that equipment would be DOA and a financial disaster for the car manufacturer.
