By all means you should have a car. Taxis for when you go out in the evenings, or to the expat functions, definitely.

When driving act like you own the road and you'll be fine, most of the taxis do. Don't become rattled by the horns honking, just go where you need to go and if that means you are driving in the dirt to pass a single car, well that will be up to you.

My own little advice is to relax when driving, as you save no time trying to get past another car. Tune the radio to 99.3 Radio 2 and sing along. I'm a rock star in my vehicle.

Please don't drive under 120 in the left lane. Cheers.
