My idea is that instead of having simply red back lights on cars to tell just when they are braking, have backlights come in the red-yellow-green scheme like traffic lights. A car's back lights would go to green when the driver accelerated, yellow when their foot was off the gas or on the clutch (for stick-shifters), and red when one was actually braking.

Pink if they are busy with a passenger, just to warn others that driving may be erratic.

how do colour blind drivers get on with traffic lights never mind this? having said that, its not such a bad idea

[po] color blind people just know that red is on top and green on the bottom. But not all color blind people have a hard time with red and green, it can be many other colors and shades.
