Give way to buses

This is the stupidest law in Queensland. I understand that in less civilised countries it’s basically the biggest thing on the road has right of way. But I was driving home tonight and this bus just pulled out of me. I started placidly raising my fist and questioning the ability of the bus driver when my wife gently informed me that you have to give way to buses. Hands up who knew that? It’s a stupid law. Here it is from the Queensland Transport laws of giving way page :

When should I give way to buses?

In built up areas where the speed limit is 70km/h or below you must give way to buses when: 

• buses are entering or about to enter traffic 
• buses are pulling out from a bus stop, shoulder of the road, or far left side of the road
• the bus displays a GIVE WAY TO BUSES sign and the right direction indicator is operating.

When a bus complies with all the above criteria, then vehicles approaching from behind must give way. It is important to remember that all vehicles, including buses, must indicate for five seconds before moving off.

It’s a dumb law. And there’s no way buses ever indicated for five seconds before moving off – but how can you prove that in the event of an accident? Does anyone time it? Is it registered in the bus’s black box so that in the case of an emergency it can be recovered to tell all… If buses are a protected species there should be something to ensure they don’t take advantage of the system.
