We have this same discussion all the time over on the Syndicate Motorsports forums.
There's not alot i can say, that other people haven't already said, apart from adding in a few stories of my own.
I work nights, and on one of my 3am 'servo runs' to get some food, i drove away from the petrol station, without indicating twice, and then doing 80 in a 60 zone. A polica car then pulled out of a side street, lights blazing, and i pulled over. After talking to me for a while, he let me go, with a warning that if i continue to drive like that, he'll be seeing me again. I was polite, and did as was asked. Now, this may not happen all the time, and maybe he was just so damn cold standing outside, he just wanted to get back in his heated SS, but i was lucky. Let me say this, now i indicate out of there
There's been many other times, some like this, some not.
Oh, and i'd like to also add, that the ACT is the only place in Australia that has the right to refuse an Engineer's Cert. for anything. SO even with one, we're not safe. Although, we are allowed pod filters, and BOV's venting to atmosphere.
Stay safe people, and keep a cool head.
