You are probably right though whats the comparison/statistics of P plater accidents to fully licenced driver accidents?
Also these laws are targeted at reducing deaths in the P plater bracket. If passenger/vehicle and time restrictions are not the answer, what would you suggest?
The problem stems from mental aspects not physical. If a bloke wants to be a hoon...driving a 4 cylinder isn't going to stop him from being one.
The government are trying to use these tactics to push more young drivers off the roads and make the figures misleadingly positive rather then approach the real issues that relate to law enforcement.
