Yet still does single digit mpg around town. If they really wanted to save fuel 
they'd build it out of aluminium and literally save a ton of weight but that
wouldn't get the Kool Kids on board.

Ie there'll be a whole heap of faults and trouble awaiting the 3rd or 4th
owner 10 or 20 years down the line and it'll probably be uneconomic to repair
if too many modules fail.

Quite ridiculous really compared to some of the other systems especially given
most of it is in the bloated ICE which many people don't use anyway because
they just pair their phone and use that instead.

Why do car companies design the interface of cars for teenagers these days
when the people buying them new are are usually 20+ years older? One of lifes
mysteries.
