Re: Missing the obvious
"Even the best put lives at risk when in control of a moving object substantially heavier than a human."
Well, that's a loaded statement if ever I saw one. Everything in life is a risk, it's a matter of quantifying and assessing the risk and deciding on the level that is acceptable. The majority of drivers are responsible and don't generally do stupid things. Most of the problems with traffic on the roads is the increase in numbers of vehicles and the reduction of traffic officers thanks to a reliance on cameras of various types (ANPR, Speed, Red Light etc.)
