You'll find you need a car right away out here as there is virtually no public transport in Qatar, save taxi's.

Despite what people say, however, the driving out here isn't too bad, as long as you know the local "rules". Basically anything in a 4x4 (normally a white landcruiser) and that looks local, has right of way in every situation, tends to not use their indicators, will under / over take at any opportunity, and drive through junctions / lights / round-abouts without looking. Know that and it's plain sailing. Driving in London is far worse. ;-)
