Speeding is one thing, doing a burnout in a carpark is different. I've done a burnout in a carpark once (when I was 16), it was mildly amusing for about 10 seconds. No idea why people do it - sad. So yeah they deserve to lose their cars. Reporting someone for speeding is something different. If you are an experienced, skillful driver, in a performance car driving in good conditions then I don't think you could be classed as a hoon for doing 160 in a 110. Now if you're 17, pissed, in a Commodore with bald tyres and 4 mates in the car then thats a different story.
