Some countries literally subsidize gasoline, but even if your country does not it probably supports oil companies with tax breaks ('creating jobs'). There also are lots of untaxed externalities like global warming and exhaust pollution.

In Germany for example(and other EU countries) you get money back from the government on your tax return for your daily commutes to work, if you live far away enough from work to qualify for commuter subsidies. Those subsidies you get no matter which transportation you use, bicycle, train, car, etc. And plenty of people commute by car when their work/home is far away and remote enough for cycle/public transportation to not be very useful or convenient.

Funny how their solution was to subsidize burning fossil fuels for car commutes to the office instead of, oh I don't know, MANDATING WFH!, given Germans are such staunched green environmentalists. Sure, let's turn off nuclear and ban plastic straws, but let's also subsidize the generation of diesel, brake pad and tire fine dust particles we breathe in, for commuting by car to work. We can't forget our car industry lobbyists.
