Speed is the number one thing trucks can do, if they slow down every 10 miles per hour, they save a mile per gallon.

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.

It won't be quite as bad as this morning, but wind gusts of 45 miles per hour can be felt on your car.

You go from zero miles per hour to 18,000 miles per hour in 8 1/2 minutes. So, it is the most dynamic ride.

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

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