Not too terribly difficult with a large hard disk instead of tape for 
recording on. Of course, it will be nice to get high capacity solid state 
disk equivilents which are more resistant to shock/impact.

How to do? Keep a rolling 75 minutes of recording data/frames. When 
signaled by a sharp impact or manually triggered, set a timer to shut down 
after another 60 minutes.

Of course, a bigger HD or other storage could allow longer recording 
times. Conversely, a smaller HD would result in shorter recording times. 
As long as the data around the actual incident itself is retained, the 
rest is just "insurance" for a time when emotions can run high, and stupid 
things can happen.
