Your experience is atypical.
Consumer reports says the average annual cost of running a used car rises to over $4000 per year by year 12 in today's dollars.
I agree electric is more expensive when gasoline is below $2 per gallon. They made sense when gasoline was $4 per gallon and likely to head up.
Ironically, the higher the percentage of electric cars, the lower the cost of oil and gasoline until the gasoline network effect collapses which is at least a couple decades away. This is because they eliminate demand for the most expensive oil and most expensive gasoline which sets the price for all the rest of oil and gasoline.
FWIW, I didn't say I only have a few thousand in total maintenance over 20 years, only ICE specific maintenance. However, I find $4000/year a bit hard to believe, unless it includes *all* expenses and gas.
I suppose amortizing consumables like brakes, tires, adding insurance costs, and assuming general wear/tear like a broken tail light, a broken windshield, shocks, a bad AC unit etc, could easily add up to another $1000/year plus on an older car, but these would likely be the same for EV and ICE cars.
It probably also assumes you drive around 15K miles/year. I average about 7K miles/year which is a typical M-F EV commuter car amount. That extra gas could be responsible for 1/3 of that $4K. Also probably assumes folks change their oil every 3K miles (rather than 7.5K which is what is recommended for a car of my vintage).
The moral of the story, with today's cost structure, the less you drive, the less paying the EV premium makes sense, yet until they get the range up on the EV, you probably won't drive a typical EV *that* much meaning the range where it really is better is a somewhat narrow band of drivers. If you want to draw an analogy to lightbulbs, ICEs are like Incandecent, EVs are like CFLs. The LED equivalent car technology probably hasn't been invented yet, but will be the one that really works.
