Only 4000? I'd be surprised if it wasn't more. I think a lot of the problem is not necessarily Qatari's as someone said, but their drivers. Let's be honest, they can come from a place that has cars held together with little more than duct tape, and then come here to earn a living and suddenly they are driving a 6 litre, 3 tonne vehicle with no real comprehension or teaching of the huge difference in stopping distances or the difference in the centre of gravity. Even if they pass their test over here, it's in a small sedan type vehicle. Also the number of people in these 4x4's who will sit 2 feet off your back bumper when you're doing 100kph. Absolutely no chance whatsoever of reacting if the lead car has to brake suddenly (usually after some idiot has moved across 3 lanes of traffic with no indicators and no real gap to do so). Video cars including undercover ones should be monitoring the roads.
