In Bangkok you can find taxis using meters specifically if you are not in an Tourist-Area, but there is still the issue with the attitude, driving-styles cleanliness, maintenance, just to name a few. Also if there is any issue it is hard to report the driver since frequently the person on the license is not the one driving.
Now with Bolt / Grab you have the drivers name and all the details if there ever is an issue which never was except one not so friendly driver in maybe 100+ rides. But then you can report this individual with details to Bolt and give one star. Good luck reporting any Taxi driver!
Bolt also shows the cost when you book, so there is no incentive for the driver to take you for a large detour. Now specifically in Pattaya I have NEVER seen any local Pattaya Taxi to use the meter, some did not even have one. So for some of the comments above where is the law applied here?
Bolt would be less popular if the taxis specifically in Pattaya would not rip-off the customers, just food for thoughts. Funny enough I get quite frequently a normal taxi when I book Bolt there and the fare is suddenly 100 THB instead of 300 THB.
