As for the majority of Chinese taxi drivers I've gotta say I met few dishonest ones. As for Pattaya motorcycle taxi drivers I think many of them are dishonest.
They don't want to give you a price upfront in many instances.

In Nanning at Chao Yang must of the motorcycle taxi drivers knew me. They gave me discounts. So as far as taxis go I'll say China is better than Pattaya in that regard.

However, you should not toot the horn for China on here. Generally speaking the Chinese have very few or no redeeming qualities whatsoever.
