It seems reasonable and practical for a vehicle's rear brake lights to vary in intensity in proportion with the intensity with which the pedal is pressed, or perhaps increase significantly in intensity if the decrease in speed is large enough.
Currently, drivers (in UK) use hazard lights to signify
intense braking.
Very similar

It seems like BMW already implemented this idea. [alepfone, Feb 19 2001, last modified Oct 04 2004]

At the risk of sounding like paragraph 37 of The Highway Code: one shouldn't activate hazard lights during intense braking, when both hands should be on the steering wheel. In my experience the sequence is: sudden obstacle - intense braking - ease off brakes or stop - put on hazard lights briefly just to wake up the person behind you. |

(Oooh, I just can't resist it!!)
Actually paragraph 37 of the Highway Code is:
"37. Before you take a horse on to a road, you should:
- ensure all tack fits well and is in good condition
- make sure you can control the horse.
Always ride with other, less nervous horses if you think that your horse will be nervous of traffic. Never ride a horse without a saddle or bridle." |
