> 35 in a 25. That is a big difference, by the way. Almost twice as fast.

1.4 times as fast is not "almost" twice as fast. 50 is twice as fast as 25; 49 is 1.4 times as fast as 35 which is 1.4 times as fast as 25.

You're correct, but it is true that 35 mph would be roughly double the kinetic energy, which probably matters for accidents.
