Yes, we use petroleum for many things, plastic, etc., and we certainly use it in our cars. Cars the auto and oil industries made sure gobbled up fossil fuels. Do we use these fuels Mr. Oil Man, yes, because for years large corporations and families that own fossil fuel producers and Detroit did all they could to block alternatives, cried they could not make cars that got better gas mileage until the Japanese showed the bullshitters in Detroit it could be done. Electric cars are coming, in fits and starts yes, but they'll be here and as the tipping point comes Detroit is seeing the light and venturing into electric. The oil companies have been complicit in our need for oil so Mr. Oil Man when you want to play the reasonable one, take your own advice and STFU.
