If you speak French, Bitume was extremely popular on the French scene (plot is that the Halley comet came with a weird disease that made everyone forget everything, including reading, so civilization collapsed and then recreated around misunderstood memorabilia). When you created your character, you also created his (starting) vehicle, within limitation of your clan in some cases (the Vikings, which were actually the Flemish and Dutch, only used tractors or buses, the Hell's Angels used motocycles only, ...). Combat was short and nasty, you could be a goner in one-two bullets. One of my players killed another because with his technical (pick-up with a machine gun behind) he cut in front of the other guy flamethrower dragster to pass over an hostile truck. "Driving test" for the dragster with -30 because, well, dragster => Fail => Crash => Explosion.
D100 system rather than D20. No fantasy and no sci-fi, it was 1980-1990 technology only. The only thing a bit non-basic was the Ants, a secret organisation who had prepared for the apocalypse by stockpiling the best the technology of the late 80ies allowed (but nothing more), had maintained it and lived in secret underground base, though they had to use the same roads as everyone to travel from one base to another.
The universe was cool, with description in the various books of what happened with Paris, Lyon, Marseilles or even the whole of Britany (with pos-apo ships rather than cars). Like all French RPG, it was full of sex, drug and alcohol.
in 2019, they kickstarted a new version in (and collected 7 times more than expected), now in production. Possibly they may translate it :
