I know most people here aren't massive retards about this, but one of the reasons I've been looking into the motorbike game is because there are far more vehicles out there that are extremely simple to repair potentially by myself and everything is analogue. I'm not that bad when it comes to vehicles and yes I do know that most vehicles currently do not rely on an internet connection DRM style to keep operational as of yet, but that may start changing soon as they keep pushing green agenda nonsense.
However with what we've seen being done to planes I'm going to play it completely safe because the elites are retarded they're probably going to be pushing people to buy electronic vehicles and this will have all kinds of ways to track your positional data as you're travelling through the country. So I'm just putting out a general PSA in that I wouldn't even get a vehicle that has digital display because that's one extra thing to go wrong that you're not going to be able to fix. Imagine having to ride several miles away just to get fuel and you realise you're fucked because an EMP device or something knocked out your digital display so you don't even know how much fuel you have lolz.
If your concern is an EMP, then you're going to want a carburetor. Fuel gauges have been electronic for ages, I can't think of a mechanical fuel gauge system that displays on the dash.
Ironically since you mention planes, if you're concerned about that level of resilience, you want an old plane. Carburetor, magneto, steam gauges, and you can typically easily dip the tanks for fuel level. They rely on electronics for almost nothing. Also still available in operable condition.
the power and electronic-destruction potential of EMPs, even from nuclear detonations are vastly blown out of proportion. you'll be fine.
