I have a idea that could help people with that all too common problem of your car blowing a wheel, and you don’t have the right parts to get it fixed up.
My idea is this: why not have it so “sometimes” a jack or wrench can be found one of the broken down cars trucks littered around your city. Maybe even a spare wheel.
After all how many of you with a car(in real life) have the parts to fix a popped tire in the trunk your car or, truck?
that and now you wont be just scavenging buildings anymore, but vehicles as well.
