For many years the National Pretend Speed Limit was fifty-five miles per hour (metric equivalent: 378 kilograms per hectare.)

I do all of my good thinking at over 65 miles per hour. The speed limit is, luckily, the same speed as my brainstorming speed.

The speed limit on most of Maui's highways is forty miles per hour, but my mother never went above thirty.

Nobody would be killed on the roads if the speed limit were 10 miles an hour.

Auto racing is boring except when a car is going at least 172 miles per hour upside down.

Don't go too fast on the freeway 'cause every five miles you go over 60 miles per hour uses up, like, a fourth more gas than usual.
