I've already paid for it... after a 15 month wait I wasn't going to leave it at the dealer.Don't get it because I doubt the taper is going anywhere for quite some time, if ever.
Unless you have a Taycan, the charge curves always mean that charging more frequently in the low/middle of SOC is always much faster than charging less frequently to above 80%. So personally I don't see this as a big deal. YMMV
I agree it's rare to need to go over 80, but it will happen, and the car should allow that, not tell you you're using it wrong, essentially.
