After yet another appalling display this arvo, I did some more research....There is a government endorsed site for reporting cab behaviour. It seems to be based on being a passenger but you can still submit complaints as a rider/driver. Some may say, what's the point. But it is better than doing nothing at all. It only takes about 3 minutes that you would otherwise have spent waiting for the netrider server. The site is endorsed by the Ministry of Transport and is: http://www.131500.com.au/customerservice/feedback/taxi.asp You will need some details including cab rego and company as well as time and place of incident. My first entry was this arvo when a cab in a right turn only lane cut left into my lane as I was on him. I braked pretty hard to avoid him and then honked. He then looked in his mirror and deliberately slowed to a stop to block me despite there being 20 cars behind me also waiting, who by this point were starting to honk as well. He then started to go again, got 5 metres and then braked to a stop at a set of GREEN lights. He was waiting for them to change so he could scoot through and leave me waiting on the amber. He did all this WITH A PASSENGER! So not only did he risk the passenger as I would have hit at about the passengers door if I hadn't stopped in time, but he sat there on a green light with the meter running. I love Sydney cabs!
