I have no problem imposing a 'tax' on someone who has put a 'victim' into the situation, in which they require extra funding by way of a victim support fund.
Your average speeding driver is not this person however. If the 'tax' applied to people who caused a crash, then I would not have a problem with this. I am shocked that the govt. would even consider this, taking into account the current climate with regards to speed cameras.
