I understand Greg's point perfectly and agree violently.
My post was addressed to subaqua.
Cars don't weigh a kilo, above 20 mph the chances of serious injury or death increase dramatically, basic physics.
There is no excuse for drivers to treat roads as racetracks, there is no room for complacency with the carnage drivers cause on the roads.
Heard about the Zero Initiative?
The Swedish stated aim with regard to road safety is zero. No deaths. None.
They concede the aim may be unrealistic, but they've achieved spectacular results:

The Vision Zero approach to road safety is highly effective. Sweden has one of the world’s lowest traffic-related fatality rates - and the statistics clearly show that safety does not compromise mobility. On the contrary, increased mobility actually depends on effective road safety.
More traffic, fewer fatalities
Traffic volume and fatality rates are partly linked to changes in economic growth. But we can clearly see that road deaths have continued to decrease despite a steady rise in traffic. This chart shows the growth in traffic volume (blue) and recorded traffic fatalities (yellow) from 1950 to the present day.
Huge potential
There are other positive effects. Fatalities involving unprotected pedestrians in Sweden have fallen by almost 50% in the last five years. The number of children killed in traffic accidents has also been cut. In 2008 the first traffic death involving a child did not occur until 22 October that year. And yet, the untapped potential remains huge. In Sweden, we could cut the death toll by a further 90% if we could eliminate technical system failures, failure to wear seat belts, speeding and drink driving - from 5 deaths per 100,000 to 0.5. This is what the Vision Zero is about: looking forward and creating strategies to take safety to new levels.
