My point being, if you want to catch someone who's speeding how can you do that without going faster than they are? Just follow sedately till they run out of gas?
Seems the statement that he was going exactly 55 ... not 53 or 58 seems hard to believe under the circunstances IMHO. You're chasing a bad guy with lights flashing and you know EXACTLY what speed you were doing and positive it was never above the posted limit.
Since when do police obey the speed limits ... especially in a chase? I've seen the vidoe's
I'd bet the woman who pulled out was surprised at how quickly he came up upon her.
Just speculation and common sense mixed together.
