Makes sense, especially when reading the overtaking part.
In the UK, there is NO "fast lane". On a three lane "motorway" (mention highway here and they look at you funny), the inside lane is where you're supposed to drive - the other two are for over-taking.
In SA, inside lane is for trucks and broken down cars, middle lane for normal people, and outside/fast lane for people in BMWs who like to check how close they can get to the car in front of them with their feet slammed onto the accelerator pedal.
Also, you're unlikely to ever be stuck behind a piece of crap held together with tape and wire in the UK. Every car older than 3 years has to go through an MOT (basically a roadworthy) every single year, or it gets scrapped. Also, every single driver has to be insured - or take the bus.
Ironically, random potholes aside, our highways and residential roads are superior to anything in the UK. They're also much, much wider.
