How do people intent to power cars during the apocalypse? I guess electric cars can be charged with solar or wind but it's not a small battery to charge. As for ICEs, stations are going to run out of gas after a few hours, and AFAIK, gas has a limited shelf life so making reserves for the long term would be a problem.
As someone that doesn't get cars nor the "freedom" they supposedly confer, I also never got that part about an apocalyptic future. To me, a car is already a burden, and I can't see why I would want one during the apocalypse.
