I can not begin to count the number of times I have come around a corner and almost smacked into a tourist on a golf cart, driving the wrong way. Happily oblivious to the fact that they are not on a ride at Disneyland, but rather a dangerouse vehicle which is capable of getting them killed. Quite easily too.
It's not like the streets aren't marked as to their direction.
Sometime they even seem to be overmarked.
And still the wayward tourist, usually with drink in hand, will merrily ignore these signs and put my life, their lives and the lives of children in the street, in mortal danger. Shame on them.
I think that this should be the only transportation tourists are allowed to rent.
