I agree, but often it's corner cutting. For example, I'm pretty sure that the 12v battery in my ID4 is a bog standard ICE 12v battery rather than a re-engineered one that is considerably lighter (and smaller capacity) like you find in a Tesla.
When SWMBO needed a new 12v battery in her Yaris hybrid, l was surprised by how small it was (hidden under the back-seat)
However, l was far more surprised by how much the damned thing cost!
I seem to recall one place quoted almost £250!
(a lot less, in the end at a main dealer!)
[*]Seat in the ID4 is a manual seat. In both Teslas it's fully electric and adjusts to the user entering the car
Our XKR did that back in 2007
Two keys (& a 3rd!)
The steering wheel retracted when the ignition was turned off, resetting to the correct position when a key was inserted
(as did the door mirrors)
The 3rd key was described as a ‘valet park’
Whether it didn’t allow boot to be opened, or…. reduced power output/restriced speed, l have absolutely no idea!!
