It's just not smart either.... I'm not just thinking safety here but you also want to ease yourself into cars not barge in with brand new powerful machines. Drive a banger you need to fix and look after for 5 years, don't spoil driving by starting out where few ever get to! I also suspect it doesn't do too well for the whole humility factor, but that's obviously down to the individual...
I'm probably upsetting a few of our younger friends so I'll shut up now.
