The rate at which the accelerator pedal is released differs between braking, lifting off to change gear, and lifting off for emergency braking.
I suggest that the lift off when I'm about to run into the back of another car is detectably quicker.
This can be detected and switch on the brake lights
fractionally earlier thus giving the guy behind you an earlier early warning.
(100ms at 60mph is 2.68metres)
The system could be semi-intelligent, i.e. detecting a driver's particular habits and trending these to re-calibrate.
Quick brake.

Hmmm... not so sure about this, but
since I've got no great objection to my
breaklights very briefly flaring when I'm
changing gear, [+]. |
|
|
I hear what you're saying [stf3], but when changing gear, I only partially lift. |
|

Daimler-Chrysler's Pre-Safe system is similar to this, and also pre-tensions the seat belts, closes the sun-roof, and positions the seats so as to optimize the air-bags. |

I suppose you could have a detector on the gear stick that senses that you have your hand on it or near it . The combination of sensor,release of accel pedel and pressing clutch does not trigger lights but other combinations that indicate your likely to brake do. |

Parrafin, you actually let up on the gas when shifting? I just keep it floored, pull on the shifter and mash the clutch...it doesn't sound too good, but I'm told it gets me an extra .001 in the 1/4. (just kidding...I'd like to keep all the pieces inside the case) |
|
|
Depending on traffic conditions, I sometimes lift partially, sometimes completely. Sometimes quick, sometimes slow. |
|
|
Sorry, I don't see this working. |
|
|
This would ruin the fun I get out of shifting from fourth to second when someone is riding my ass. |
|
|
A simple single axis accelerometer could do all this for you. |

Thanks for the link [bristolz]. I suppose the main down side is it's less likely to be shunted from behind, so less chance to feign whiplash and get a massive payout. |

|
[contracts] you find it more fun not to brake? I tend to hit the brakes hard, then downshift and floor it. |
