One of the "must-do's" in Doha is to get a tour company to take you for a trip through the dunes in the southern part of the country to the Inland Sea. You cram into a Landcruiser and then drive south to the end of the pavement, at which point the driver gets out and lets a lot of air out of the tires to improve traction on the sand; this is where the fun begins. These guys drive crazy in the desert, up and down dunes at crazy speeds.

What is particularly amazing about the experience is that there are lots of other people out there as well, just being crazy. If you search "dune bashing accident" on youtube, you will get an idea. Don't know if I would do the same in my car, I think this just adds further support to the rule that you should never buy a Qatari used car.
