Don't get me wrong, i hope you beat the ticket but if you need to coast down to less than half the speed limit all the time to get good MPG i wouldn't consider that to be safe.
I know how other drivers are, always in a hurry, and even though they are idiots and want to ride our rear bumpers all the time i don't think having them involved in an accident or hurt/killled is worth it.
