I would like if cars would somehow indicate how strong they are braking. Like a meter filling, the light starting to blink after a certain threshold and blinking faster etc.
Yeah, but often you don't know how much braking is applied. I'm sure that my idea is wishful thinking and would show some other negatives.
Another idea I just had is, that maybe, in a connected car future, cars will just share their data about how much they are braking automatically live to surrounding cars, so a car behind can react automatically as well.
This would be a really cool standard! I only wish it would work here in the US, where our brake lights have to pull double duty as turn signals. But in sensible places like the countrirs in Europe, this would be dope!
