Ok (guess a tourist term), please explain.

It's easy to grab a taxi, stick a knife in your body, kill him when he (she) isn't looking, and then we drive. Hee hee, I'm fine, hehe, just kidding. I'm not a gangster. The real answer is: a taxi. Although some terrain will beat you, you'd better sue in court (you'd better get the evidence, or you'll sue for nothing).
