Your post lacks common sense for these reasons.
Not when they are in a high speed pursuit.Police cars are subject to the same speed limits as everyone else, and don't pull over people on the drag strip.
Maybe we can have small engines when we dont have so many crazy assholes driving around that cops have to chase after. They are given fast cars and guns for a reason.....so they can protect your ass from all the bad guys.Other nations use smaller sedans with 2.5L engines that get 30mpg. How many billions could be saved that way?"
