As a species, people perceive brightness non-linearly and it even differs between individuals and with age. You would want to have a group of break lights could you light up in relation to the braking Force. 30% brightness is hard to figure out but one of three brake lights is easier to grock.

I thought of such a beast for a long while... that it would be cool to have an LED array that increased in numbers based on brake pressure.

Aside: anyone else ever been driving behind a large vehicle with the brake lights out? That's a not fun exercise right there.

how does this improve the driving experience?

Is "i wonder how hard they're breaking" really a problem?

People drive too close to each other already

		When you're on a highway at 75-80mph in Phoenix towards the evening sun, and see a couple brake-lights ahead it can help understand the massive difference in terms of do I need to slam my own brakes or just take my foot off the accelerator alone.
