Yeah, it is a bloody stupid law. There should be a competency test you can take after say 3 months of riding that removes restrictions on your license, given I've seen some fully licensed riders who don't have a clue what they're doing, as well as the fact you touched on that you can write yourself off on a gutless postie bike.
I'm just pissed coz of the circumstances I was exceeding the limit - the f**king clowns in front of me dead set had no f**king idea what they were doing. I gave it a blat to overtake them (thinking it was still 90kph) the moment I got a chance, for my own safety. Alas, this was my undoing lol
