It is in everyone's interest to reduce the
number of serious and fatal traffic accidents

The problem with that is that only 5% of RTCs have exceeding
the speed limit as a contributory factor, while 42% have driver
failed to look properly as a contributory factor. For fatal accidents,
loss of control was the most common factor, at 34%. Speed is
easy to measure, which makes it an easy target, but a serious
attempt to cut accidents should target bad driving.

Easier said than done.

What makes most sense it to make accidents more
survivable and to redesign the road system so that
accidents are minimised and that is what has been done.
