If you have to speed up significantly to over the speed limit then presumably the vehicle you are overtaking was already close to the limit so why do you need to overtake?

[NB Reformed speeder here - I used to speed a lot, but then got a ticket and decided to stick carefully to the limit at all times, which actually means less stress, less fuel used and I haven't noticed arriving places really any later. Have almost got in fights a couple of times though!]
