This would allow you to see not only when people are stopping, but when they're accelerating as well.

When just cruising it would just be off like a regular brake light. I'm not sure if this would be useful or not.

Not useful for those with red/green colorblindness.

Probably this would be left behind when the cars get networked. You may not know but your car will.

Just have a dash range finder, if your still keen.

One [+] but how about when they are reversing?
-- not_morrison_rm, Oct 02 2016


I dunno, [doc]. If a car ahead is braking, I need to know about it. If they're accelerating, I only need to know about if they have, for example, kidnapped my dog and I am in hot pursuit.

Given that the latter is unlikely to happen (our dog is very grumpy and remarkably stupid; I'd ask them for ransom to take it back), I'm not sure it's worth adding to the optical noise.

//our dog is very grumpy and remarkably stupid//

It's not just your dog Max, all dogs are stupid. As I've said before: If the forehead's a slope, the critter's a dope.

And yes 8, cats are just as stupid. (refer to maxim above)

(I'll pretend I understood that so I don't look stupid.)

Yes, I was just thinking that.

(Pretty cool that with these new browsers, somebody told me that parenthesis make words invisible to others, so I can say whatever I want and nobody else will see it. Ha ha! Suckers.)

At traffic lights, knowing the car infront's accceleration means, as a driver, you can stay closer and allow more people behind through. On jammed motorways, an indication of acceleration might make for a more gentle traffic waveform.

Needs be hooked to tire rotation: acceleration green, deceleration red, reverse white... regardless of driver input.

// I'm not going to tell the intercalary you said that //

This particular iWord must be a Britishism, unknown to Americans. Well, unknown to me anyway.

February 29 is an intercalary day. Leap year is an intercalary year. Informing the intercalary of something.... nope, doesn't scan.

What is an intercalary?

^ I don't see your point. In that case, normally there would be a red light followed by nothing when he takes his foot off the brake and steps on the gas. In the case of a red/green/white indicator, there'd be nothing when his foot comes off the gas, then green when it hits the gas (and the wheels' rotational speed increases).

Oh, driver's input is also signalled so you can tap the brakes as a headsup.
-- FlyingToaster, Oct 06 2016


Nice idea, but this would never work - as you accelerate, the green light would become red-shifted from the perspective of the person behind you and they would just see a murky brown light.
