I have to admit Bob (and the other well-written replies) you’re swaying me to the no-rear-bumper side of the argument. What better way to learn not to be an ass than to land on your head? If all we’re doing is trying to encourage better, more sportsmanlike driving then I agree. From a safety perspective though anything that helps prevent head-and-neck injuries should be encouraged. I wear a collar even though they’re not mandated, and will likely be buying a 360 device.
Where the CIK is concerned though the rear bumper now becomes a liability issue. If they remove it then they’re knowingly risking more rollovers and will be blamed for someone’s child being injured. I don’t see that happening.
