I've been thinking about this a bit since I posted.
Last night DH was training with our local fire brigade and they nearly got taken out by a hoon. He was doing burn outs past them, and almost side swiped a fellow member, leaving him very upset and shaken. They got the rego, and Dh called the police. But because they couldn't "see" who was driving, because it was dark, the police told them they couldn't do anything about it. They went to the house where the car was registered, where the person denied the car was being driven, even though the bonnet was still hot. The police returned to the group training to report back.
Tougher laws are needed. No tolerance is needed. I feel the same way about people who flash their high beams to warn others of a speed camera. I often wonder if a speeding driver is flashed, they slow down, and then go on to cause an accident where someone is seriously injured or killed. Is it worth flashing them to avoid a ticket? Because you're actually flashing to work against saving lives. If they keep getting booked for speeding, then they will either learn their lesson, or lose their licence. Either way, the roads will be safer.
