Cars are bad, but there are far more people driving a car than working in the automobile industry. The former has a better claim to societal health than the latter.
Cars are good in some circumstances, mass transit, in other circumstances. One size does not fit all.
Small, inexpensive cars would also be good in some circumstances, but the US auto industry, for some reason, struggles to offer something as compact as Honda Fit, or at least something as reliable as Toyota Corolla.
