Or more to the point, that younger drivers tend to be more exploratory...we have all been there done it...donuts and driven dangerously on roads in excess of the speed limit (although I was in a 1.1L Fiesta with four odd tyres and not a Zed!) You do it when you are younger because you havent done it before and you want to try it out. Being older, wiser and generally slower makes you less of a risk
I had it at the weekend, dropped Rebecca off in Reading, then driving back to Windsor coming up off a slip road had some chav in a beat up Audi tail gaiting me, I started to blip the throttle and the Z roared and started to pull away but as I hit 60 just plopped it into 4th and cruised on the inside lane as I got onto the A road. He came tearing by on the outside and I could see him checking his mirrors, over his shoulder, really like he was in a big race or something - he had a proper serious face on and probably rushed straight off to tell his mates how he beat a 350z in his N reg Audi 1.6 diesel - to be honest, just laughed inwardly at him and carried on my merry way. Suspect he is more likely to wrap his Audi round a tree before I am ... (thats hexed it now!)
Hope we haven't scared off the OP
