no they dont. as cars sit unused, their lifespan also shortens. when cars break down and they get too old, the manufacturers design them so that you cant get parts and must buy a new one which is totally incompatible with the one you already have. this is not efficient, this is good for $$$.Durable goods have a life span. The least you use and abuse them, the longer they will last.
Maybe you just need a bicycle or a motorcycle. If you need a car, get a smart car. But you might have trouble getting you head inside.
yea there should be a 1 seater car which is safe, amongst other things. and the market doesnt provide this as far as i know.
