> In England at least the speed limit is the absolute maximum speed at which you drive.
In theory this may be true but it's absolutely not in practice. It's not uncommon to see people at least 20mph over the limit on motorways. On the M4 that is practically the norm.
Try sticking to the speed limit through long 40 or 50mph roadwork sections. I've done it for a laugh before. You end up getting overtaken non-stop including by trucks which, to me, feels far more dangerous than just fitting in with the prevailing speed.
