If they try to fine you for excessive use of acceloration, tell them you were trying to get up to speed as quick as you could to keep the traffic moving. The things i hate most are slow drivers. Like doing 60/70 in a frickin 80 zone.
That hooning law your describing, wouldn't it be that if someone has a thing against you they could dob you in just for the hell of it?? Sounds unfair considdering there is no proof.
Personally, i pelieve there shouldn't be speed limits. There should be speed recomondations. Like "we recomend you do 60 here, but you can do more, f@$k up and you'll pay."
Also, on old people. I do agree that some need to be retested and that they shouldn't have their license, but some, like my old man, is quick off the mark and does follow the speeds. You can't really be shitty at the driver infront if they are doing the speed. Unless your in an 80+ zone and they're not overtaking, only hogging the right lane.
