What I'd like to see is honest statistics of road accidents and fatalities by km driven, broken down by heavy trucks, passenger vehicles and scooters.
I suspect driving a car in Thailand isn't nearly as dangerous as most expats think it is, and riding a scooter is a crapshoot in any country.
Once I got used to Thai road etiquette, I had no problems in my pickup.
Edit: And I'm a much safer driver back home, where the defensive driving skills I learned in Thailand stay with me.
