I'd be curious to hear where you think all of that complexity has moved. While ICE are definitely more reliable these days than they were 50 years ago, I don't think the major issue is with them directly, but with the sheer amount of ancillary components they imply - ie belts, alternator, fuel injectors, spark plugs, transmission, radiator, starter motor, starter battery, etc. Those are the source of the vast majority of problems and maintenance for ICE cars. EVs need none of them. For electric vehicles, I'd view the cooling system as the largest source of complexity. And I think those will simplify as batteries become better designed (lower internal resistance from tabless for instance), more dense and less expensive. I think it's important not to conflate Tesla and electric vehicles. They are building luxury vehicles that have the added complexity and added unreliability that implies.
