I grew up in Saudi and the highway is similar to an autobahn.
The posted speed limit is 120, but you'll regularly get overtaken by people doing 160-220 km/h. In certain cities they'll throw you in jail for a night if you're doing over 160. But I've done 240 in my e38 and gotten away with it.
In Canada I would never go over 140, so don't hate!
