I mostly agree, Dylan. If you're doing over the speed limit, you need a heightened level of attention to the road and the other cars on it. The faster you're going, the higher that level of attention needs to be.

However, on my trip to CES this year, I saw some places in Nevada where it was was perfectly safe to do 100 or more and even be able to zone out a little bit. Perfectly flat straight road, visibility for many miles in every direction, not a car in sight...
