When somebody stepped into the road in front of my car, the brakes were already on before I could get my foot to the brake pedal. That sold it right there.
But my lane departure warning is audio only and doesn't really compete so well with loud music. A vibration through the steering would work much better.
The car also has a system to monitor driving and tell you to stop if it thinks you are unwell, tired, drunk or otherwise incapable of being safe. Happily I've never seen it work.
Biting the hand that feeds IT
