Yeah, similarly, one could make the mistake of walking. But even sneaker treads use rubber. Same poison!

You actually can get bikes for free pretty often, especially if you've got the ability to turn a wrench.

And while modern tires probably do incorporate some fossil 'fuels' (technically not fossil fuel if you're not burning it, by the way), they don't have to. Old school tires are made from vulcanized rubber, which can be made by reacting natural rubber from a rubber tree with sulfuric acid and heat. No fossil 'fuels' involved.

Dumbest internet comment today. Well done!

Bike tires don't usually weigh more than 300g.

Car tires usually weigh more than 7kg and you need 4 instead of two.

The only slightest bit of an argument here could be for trains.

I also need maybe 5 specialised tools to service my bike (which is veeeery easy to do compared to doing it on a car) and those tools together cost less than 200€. Then I spend around 200€ a year or less on parts to service my bike, and I use it to go to work every day.

My car is sooooo much more expensive than that, even though I do most stuff myself.

Bicycles have less mass than a car and therefore need less fossil fuel for their tires. Bicycles are objectively cheaper to buy, maintain, and run than a car, even if you go for the average expensive bicycle and the average cheap car. There just is no way to make the car come out on top when it's about costs.
