I highly doubt that people REALLY saw a 959 in California. You're right,
there were two that were impounded in San Francisco, and one of them was for
Bill Gates. However, Bill Gates doesn't work for Apple and Microsoft is in
in Redmond, Washington. Unless someone saw him driving it up to Washington
(if it was even released), it's doubtful people saw it much in California.
BTW, it's not that the 959 wouldn't pass the crash test test, it's that
Porsche didn't want to waste/total a very expensive 959 on the crash test in
order to sell a very limited number of 959s.
