One of the very few tractors that have permission to drive on the Autobahn as it can go to 100 kph. It's a Hanomag from 1964.

Where does it say that the speed limit is 100 kph??

You lot are so precious about the strangest things. Punishment for killing or injuring someone whilst drunk means NOTHING to the killed person and almost as little to the injured person. The increase in distracted driver syndrome is due to the increase in distractions not a decrease in drink driving. Safety issues like this are prime examples of where heavy handedness and public display of such is most effective. Fuck these a-holes. Rights such as freedom etc are not inalienable. In Australia if you refuse you are charged as if you were over the legal limit. No ifs, ands or buts. Driving 2 tonnes of metal around at 60-100 kph is not an inherent right of man but a responsibility to be taken seriously.

Drove a Hilux on a road like that for the last 7 years on and off. Never got stuck so bad that I didn't eventually make if out. Heck of a truck. To bad it belongs to my boss.
..not so stable >100 Kph on the highway though.

If I'm not mistaking, that's a German Leopard2, about which is often said "you have to drive it like a pimped out Golf-GTI.
The "official" top speed of this bucket is 68 kph, but it's more or less an open secret that even the standard peacetime version can get up to 80kph or more. There even is kind of a legend about one crew that managed to hit 100+ kph on a long descending straight after some fiddling with the engine...
