Sounds like a neat idea and potential fit with certain niche market. But I would be surprise if the answer is not just drive slower in most of the cases. In that case do you still want more specifics like brake timing? Optimal speed given current traffic condition, visibility, and curvature?

Stuff like that but also near misses. Like, "you cut off another car and they had to slam the brakes."

There are also subtle precautions that not everyone knows. For example, I was taught that when waiting for traffic to clear for a left turn (in the US and other right hand driving countries), I should keep the wheel straight until immediately before I accelerate. That way, if someone rear ends me, I go forward rather than left into oncoming traffic. I suspect there are other techniques like that that I'm not aware of.

Owh that's kinda cool, Ive never thought of that. Perhaps Im constrained by my thoughts, but I think for it to be practical it requires detecting driver's intention, which seems difficult to achieve by using only vehicular sensors data.
