This depends on where you are. A lot of "regulation" appears to me to be monopolistic pricing because there were no other choices. I'm in Australia so the below is my experience. Moving to Uber as I have means I don't have to pay the ridiculous 10% to use a card. Originally the only way to pay card with a taxi was to use the company "cabcharge" who put their terminals in the cabs and the 10% was charged anytime card was used instead of cash. This has nothing to do with regulation and there has been an investigation started around it. Further to this the cab companies are charging $2.50 (flagfall) + ~$3.00 (booking fee) if I book through them online or over the phone. The booking fee doesn't go to the cabbie, just to the company for picking up the phone. Uber charges me $3.50 flat. Once again, not regulation.
