This is like compensating purse snatchers because the promotion of mobile payments reduces their income. Sydney's taxi is a shame to this wonderful city. I still remember when I first just arrived in Sydney, I took a taxi from the airport to Waterloo and was charged $95, which made me fearful of Sydney prices. It took me time to realise that I had just run into a scam and that the ride should have cost just $20+. Now…
I don't know the situation in Sydney, but where I usually travel, it's the unlicensed taxis that overcharge and scam people, i.e., not the real taxis.
Licensed taxi companies charge standard fares.
