So why then when a road accident occurs they clear things up much
quicker?

They aren't. Up here in the Midlands its quite common for roads (I'm
talking
major commuter routes, not country lanes) to be closed through the morning
rush hour following fatal RTA's in the early hours.

Only car-on-car. Remember train crashes often see the line closed for days.

Pedestrian killings are regularly mopped up and ignored within an hour or
two.
