> EV servicing is cheaper and I do it less often.

Most EVs need serviced every year and it's about £300 to do so. This is a ridiculous amount.

What do you need to get serviced every year? Do the tires wear out that fast?

They need the oil and coolant changed apparently, or they won't warranty the battery.

Mine needs a set of tyres every few years, a set of brakes every few years, and an oil change or two a year. None of this is especially expensive.

Oil and coolant? No, someone has lied to you. EVs do not need either changed.

They need coolant for the battery and motor which degrades, and they need oil for the gearbox.

I guess you're in the US, where "lifetime oil" is a thing. Expect the gearbox to be scrap once it's a little outside the warranty period.
