I suppose it depends on how easy it is to change.

When I read "interchangeable batteries" I imagine a pretty simple procedure: open hatch, pop out old battery, put in new battery, close hatch.

When I read "install car parts" I imagine a procedure at least an order of magnitude more difficult requiring knowledge and experience working on automobiles.

Changing batteries is a task nearly all people have done at least once by the time they start driving. If changing the batteries in your car is as easy as changing the AAs in your Game Boy then I imagine many people would be willing to do it without thinking twice.

If it is truly that simple then I think the risk of screwing it up is also considerably less.

I mean, you know, it's not the same size and doesn't serve the same purpose, but today people's cars have batteries in them and you can walk into Sears and buy one. I assume the battery for an EV is huge and not conveniently located though.
