> From the worst in 1937 (29.357 per 100K pop) to today (10.345 per 100K pop), and falling by on average 2%/year since 1996 (was 15.8599 in 1996).

Yet, the statistic is still twice to thrice as high as for other car-heavy nations like Germany or the UK, no matter whether you go by incidents per pop, incidents per vehicles or incidence per miles driven.

There's a lot of room for improvement outside technical gadgets.
