Highly doubtful. In seven years and over a thousand cab rides in Taiwan that never happened to me. One one occasion my wallet fell out and the driver even called me to give it back.

Ripping off the foreigner is more of a mainland China thing.

Actually, I had no problems at all in Shanghai with the cabs (aside from their ostensibly "crazy" driving).

Anyway, since I'm not going to provide proof, you don't have to believe me.

Actually, ever since I posted this comment, I've received several emails from other HN users telling me of their Taiwanese cab driver rip off stories.

Get rekt, Taiwanese sympathizer.
