To amplify slightly—Another way to shave off reaction-time is to predict when the car ahead is going to brake. In particular, there’s a common case where car A brakes, causing B to brake, causing C to brake. There’s a fair bit of ongoing research into so-called open road platooning, the premise of which is that a computer in car A should tell B,C, and succeeding cars “I am about to brake” so that C doesn’t need to wait for B to react before beginning to do the same.
It’s neat stuff. And given that self-parking and self-driving cars are starting to enter the market, I think we may see it deployed within 20 years. At a guess, commercial freight trucks will be early adopters.
