I saw the episode when it originally aired as well, and I quite distinctly recall mentioning to my buddy that it was silly to estimate the range by the usage on a race track, since nobody would, or should, drive like that on public roads.

[Shot of Tesla driving slowly along track] Oh I don't believe this, the motor's overheating and I got reduced power.

[Shot of silver Tesla in garage with doors open] Only to find that while it was being charged it's breaks had broken. So then, with the lights fading, we had no cars at all.
I haven't followed the case closely, I have no idea how this specific segment holds up.
