Whining noise
Understand that the "prototype" is just that. Under the skin is the power train and battery pack of a Roadster. We were going no faster than 25 or so miles per hour and the whine (which I did not notice until you brought it to my attention) was from battery cooling and the power steering (since the fans weren't working). The whine was not really noticeable while we were on the test drive.
Yes, foot space was at a premium on the drivers side but, as Dan mentioned, the interior is going to change.
