Sorry mod, just one more for Vostok since he was asking. A proper study done by NHSTA. Not the cherry-picked data used by our authorities where every crash investigator ticks the 'speeding' box and equate 50%+ of crashes to 'speeding'.
Table 8, Page 23: Link ->
Study (NHSTA)
69.9% Intersections, driving onto edge of road, crossing lane lines.
17% Other cars in line (stopped, same direction, coming opposite direction)
5% Travelling too fast
2% Poor road conditions
1.2% Vehicle problems.
It makes sense to me. Intersections cause crashes. Driving out of your lane causes crashes. Humans infalability causes crashes. Very few crashes are caused by the simple act of 'speeding', especially low-level speeding, as a crash caused by excessive speed would usually require the driver to lose control of their car around a bend.
Don't believe that 63 in a 60 zone (hello Victoria) is going to kill the fairy penguins.
