With 1.2 billion vehicles all converting fossil fuel into large amounts of heat does this contribute to global warming? I have not seen it discussed.

I was under the belief that carbon dioxide,, methane and especially water vapor were the drivers of rapid global warming. It seems logical that the exhausts from 1.2 B automobiles would likewise increase these gases and hence contribute to global warming. From the current, somewhat hysterical hype about SUV's, jet aircraft and things like cow farts also contributing to global warming, one has to wonder if some tipping point has not already been reached and the Earth will continue to warm beyond its natural warming cycle. Perhaps the real driver of global warming is too many people and their related lifestyles?
