Depends on the situation. On open interstate, the limits could probably be higher. In rural areas with little traffic, I don't see why speed limits are necessary. On an open, almost deserted interstate, say in Nevada, Wyoming, Montana, etc...I don't think it would be particularly unsafe to cruise at 100 or even 120 in a sports car, though I wouldn't do it with an SUV, which for some unknown reason, Americans are obsessed with.

Problem is, unlike Germany, we design everything here for the lowest common denominator. Instead of requiring driver skill and designing a system around it, we do everything necessary so that very poor drivers can still drive. I say raise licensing standards, and raise or in some rural locations eliminate the limits. It would kill two birds with one stone (actually three...eliminating unskilled drivers would probably be the end of Toyota).
