Driving tests effectively don't exist. My students can look pretty blank when presented with examples of Western eccentricity, but you should have seen them trying to get their heads around a story of a British clergyman who'd failed his test on a number of occasions. No-one fails a test here.
Another factor is the insurance regime, which effectively means that we're subsidising the kids in the landcruisers.
But what upsets me most about the driving here is the total disregard for morality, even on the part of the authorities. The government's safe-driving campaign is directed only at Qatari drivers who might kill themselves, whereas most fatalities are, of course, pedestrians & passengers, especially children. It's the impatience and barging in front and the vicious, aggressive selfishness of the driving here that most appals, and if that isn't a matter of moral behaviour, I don't know what is. And I've never seen an Islamic moral tract that dealt with that subject.

Qataris assure me that driving is worse in Saudi.
