A trucker who experienced an incidence every 100,000 miles or so would be out of trucking in less than 6 months... or about 300,000 miles.
Most truckers have driven -millions- of miles incident free.
Lets see .. what did I experience in less than 1 hour of driving down an interstate last week?
1. Multiple trucks rapidly changing lanes, in traffic, without indicating because the truck ahead of them was doing maybe 5 mph slower than they wanted to be, and they was "just" enough room between cars in the next lane over. (And I have experienced this in heavy rain just as I was about to pass truck)
2. Multiple trucks attempting to pass other trucks, but totally underestimating the power they have and causing rolling roadblocks along the interstate at speeds well under the speed limit.
3. Multiple trucks weaving almost off the road at alarming rates for no obvious reason (I can only assume the driver was reaching for something in his/her cab - alternatively they were not 100% awake)
4. Multiple trucks tailgating cars.
Yeah .. none of these were actual "incidents", but they are indicative of truck drivers not having an understanding/respect for the rigs that they are driving, and foretell possible future incidents. Things would be a lot nicer on the interstates if all of the above were eliminated.
Hmm maybe we could sync multiple trucks together, and put them on a special road all of their own. That would eliminate all of the above issues. We could give them some snazzy name .. maybe "Trains" of trucks!
