How come both petrol and diesel cars still exist? Why hasn’t one “won” over the years?

I’m thinking about similar situations e.g. the war of the currents with AC and DC or the format wars with various disc formats where one technology was deemed superior and “won” in the end, phasing the other one out. How come we still have two competing fuels that are so different?

Diesel is better for engines that run mostly in a steady state, like trucks, semis and trains. Gasoline is better in stop-n-go applications, like most passenger cars.

In terms of passenger car use, gasoline has almost completely won out. Conversely, the same is true for diesel in commercial/industrial usages.
