Believe it when I see it. If your causing a nuisance then yeah I can see cars being confiscated but you can get them back, not like theyre going to crush them...
Id say its good reason to tow a car away for BUDWRX, firstly he wasnt clever enough to know that you shouldnt overtake on double white lines and he clearly wasnt clever enough to wait until there wasnt a copper around to do it.
The double white lines are there for a reason, the police didnt put them there. You overtake your doing it in a dangerous area and people overtaking in dangerous areas deserve to have their cars taken off them if caught as theyre not only endangering themselves.
Now Im not saying Im whiter than white, far from it, Ive pushed my car about before but its all about doing it safely and sensibly. Choosing where you do it and in what conditions blah blah....
