So why did it break down?
And why does the title of the video say "Model S Plaid
Electric Prototype"
The point why for example BMW exploits the m5 as a ring taxi is to show it can drive a track at high speed any day, all day long.
Not to show how fast they can have a sedan drive around a track and subsequently have it towed off the track
I mean this is better than a few years ago when the model S couldn't even complete 1 lap without going into all sorts of fault modes protecting the battery, but it seems that progress is....slow.
