After having been in Doha for only a couple of weeks and driving in this traffic I have made a few observations:
1. Car manufacturers could cut the costs of vehicles shipped to Qatar.
2. They don't need signal lights (they are rarely used)
3. They don't need overspeed indicators (they are ignored anyway.)
4. They don't need seat belts (for the same reason as no.2)
5. They do need heavy duty horns and bigger brake pedals.
6. The Qatari people are very nice but are probably the world's worst drivers.
7. Traffic circles should be abolished because most drivers here don't know how to use them.
8. Driving schools should be under the NASCAR or some such Race car organization.
9. Knowing how to take a traffic circle at 120 KPH in a four wheel drift is mandatory.
