The likelihood of that happening where I live is slim to none.
I'm not quite sure what you meant by that.
Are you saying you live somewhere where people who drive fast, but well within the confines of their car's capabilities, are incapable of focus - or everyone who drives fast there is distracted and at the ragged edge of their car's design?
The german autobahn doesn't live in a physics bubble, and yet those derestricted stretches of road are perfectly capable of hosting a high volume of cars traveling well in excess of 100 mph all day long.
That should set alarm bells ringing for trying to build an argument based on speed alone.
I like to look at data, so here's a link to the UK reported road casualties report 2011
Failed to look properly was again the most frequently reported contributory factor and was reported in 42 per cent of all accidents reported to the police in 2011. Four of the five most frequently reported contributory factors involved driver or rider error or reaction. For fatal accidents the most frequently reported contributory factor was loss of control, which was involved in 34 per cent of fatal accidents.
For accidents where a pedestrian was injured or killed; Pedestrian failed to look properly was reported in 59 per cent of accidents, and pedestrian careless, reckless or in a hurry was reported in 25 per cent of accidents.
Exceeding the speed limit was reported as a factor in 5 per cent of accidents, but these accidents involved 14 per cent of fatalities. At least one of exceeding the speed limit and travelling too fast for the conditions was reported in 12 per cent of all accidents and these accidents accounted for 25 per cent of all fatalities.
Over 60 per cent of fatalities in reported road accidents had driver or rider error or reaction (which included failing to look properly, loss of control and sudden braking), reported as a contributory factor leading to the accident.
Another way to read that data is that exceeding the speed limit was not a factor in 95% of accidents.
And the 5% where it was a factor does not differentiate for the car's capabilities, the driver's focus, or the surroundings (eg 50mph in a heavily populated 30mph zone vs 100mph with good visibility out in the middle of nowhere).
