FuryMakerWhy haven't car manufacturers standardized automatic brake lights when a built in accelerometer detects deceleration?
I personally think cars should have two brake light switches. one for when you’re pressing the pedal at all, and one for when you’re slamming on the pedal.
that way the people behind you know if you’re just slowing down a little or actually braking.
blackn1ghtMost modern cars now put the hazards on automatically when the driver brakes hard.
Source? I have never seen a single car that does this.
It’s a fact.
I’m a truck driver in Germany, and even my Volvo truck turns the hazards on under hard braking.
In Europe it is required for vehicles decelerating faster than 6metres/s^2^ and I believe some vehicles might activate their fog tail lights too.
