> I was recently in a taxi where the taxi driver said a number of very racist things, directly insulted me, my fellow passenger and pretty much anyone he came into contact with during the ride (other cars, pedestrians, etc) and swore repeatedly.

Please do always reprt this! I know you shouldn't have to; I know it happens far too often. But please do report it.
