As previously stated this is being implemented so that P Platers can drive the NEW range of SAFER turbocharged cars. In saying that then why not keep the OLDER cars off limits such as what is in place now so they opt for these new VW's, Audis, BMW's and the sort.
Yes these are indeed safer and education and training will also help. Therefore all combined for safer driving.
Driving a 20+ year old car just cause you can will not help the issue of creating safer roads for the younger generation.
