Cars already have lots of wear items and a mature service industry for them. If I can reliably get at least 50k miles out of it, then I wouldn't be all that bothered, as this is not likely to be an expensive part or service.

> mature service industry for them

The car service industry is a scam, and I am glad that EVs require minimal to no servicing that cannot be easily DIY like tires and brakes.

so apparently on the BMW i4s it requires a rear subframe drop which isn't going to be cheap (10s of hours).
