That is an interesting analogy, but it's pretty misleading. Tesla happens to be locked down but not because it's electric. It doesn't need a turbo, that's like being upset you can't put a new zip disk in your SSD. The engines are fixed ratio, that's a more direct control than using a gear box. Electric cars have either simpler transmissions, or no transmissions at all. In general that means easier replacement, or not having to replace anything, surely a positive, right?

Electric cars are capable of being simpler and more alteration-friendly than ICEs. They just cost more.
