I think that's exactly what happened, that we got a driver who was more interested in 'scaring' us than anythign else. We were never presented with an option, and he ignored my mom when she tried to tell him to take it a bit easier- in fact he made fun of the other car ahead of us who was taking it easier as their passengers were 'scared'. Maybe it's not the tour company in general, however I do have to judge them for hiring inexperienced and dangerous drivers.
