Good write-up but basically it's just like calling a cab(but a very nice one), or getting a nice rental.
I think this is BMW's sneaky way of testing the market acceptance for when we won't want to dump a lot of cash into an expensive vehicle that just sits in the garage for 10-15 hours each day. Especially handy for those who don't long distances and who might also consider E-vehicles constantly needing charging. I can see it coming.
If and when it becomes the norm, there won't be many driver enthusiasts left, just drone worker bees.
