EVs are cheaper and they're going to be getting a LOT cheaper over the next 10-15 years.
It's not that they're going to be alot cheaper, it's that the cost of ICE vehicles is going to be forced upwards to make those costs of new vehicles similar based on manufacturing limitations and continued strong demand for them. That's already been happening for years. If those manufacturing limitations are taken away and the incentives are removed, EVs are more expensive.
And I stated EVs "are not the answer" on a global scale multiple times much earlier in this thread based on the limitations they themselves have with battery technology, the waste streams that scale of production would generate, etc.
The notion that EVs are cheaper to maintain is based on the fact the timeframe most non-engine related components of a vehicle need to be replaced (besides the routine tire/brake replacements that are increasingly more $$$ for any type of vehicle) falls in line with the typical lifespan of an EV battery. Drive an EV until the battery needs replacement outside of its warranty and it's time to trade it in (unless you want to drop $8-$20K for a new one to throw in your ~8 yr old vehicle). So instead, people with the kind of means to buy an EV in the first place just buy a new one for close to six figures and say "well, it's cheaper to maintain". If well-taken care of and maintained, ICE vehicles can remain on the road just as long if not longer than EVs without being stuck with the decision to replace their engine or buy a brand new vehicle instead.
