nick, that's my point -- there are smart folks like you, and there are dumb ones. Highways have to be designed with dummies in mind. Product design is the same thing -- some of the customers will be foolish, and the designers have to anticipate that. A driver's license is not an IQ test.
This is why there are so many safeguards on consumer products. It is annoying at times, like those darn child proof caps on pharmaceuticals. There are no kids in my house, but I have to suffer with those things because foolish people do not keep their meds away from little kids.
And the problem with highways is that if the designers don't protect idiots from themselves, the idiots will hurt innocent bystanders. The RV will hit the bridge, and the folks behind the RV will hit the wreckage.
