Technology/Nannies alone are NOT the answer, EDUCATION and RESPECT for your vehicle and others is..end rant
Speed does not kill.
Stopping in an unexpected manner from speed is what kills.
And people who are not competent to control a car at speed (and the less common, are responsible for a vehicle not capable of managing above a certain speed) are the danger, not the magnitude of the readout on the dial in front of the driver.
But until drivers and pedestrians get their heads out of their posteriors and start paying 100% attention to what they are doing, we're all at the mercy of those data points Philster spoke of.
I'll probably regret saying this, but too many of those data points represent "thinning the herd" - people who unfortunately didn't learn before it was too late. The rest were statistics because someone else wasn't doing what they should have been (driving instead of sleeping, texting, talking, showing off). For the latter group, I am truly sorry. But limiting my
speed, or otherwise automating my
drive will not help. I tend to drive while driving. Besides, one can still quite nicely kill a pedestrian, or another, driver while going well under the speed limit.
I know, I know - responsibility for one's own actions. What am I thinking???
Control the driver, not the vehicle!!!
