direction of the sun, would you still want one? I know I would. My reaction would be, boy that sucks, but can't I just add the equivalent of a sun visor to it? I have one in my car.

There may be legitimate reasons why PRT will fail, unrelated to politics, but this video seemed like it focus on something pretty minor.

Actually your argument about Gullwing doors I think is a perfect example. There are some cars today with Gulllwing doors that are pretty sweet! So if somebody offered you a new mercedes 2011 or some exotic sports car that has Gullwing doors, would you say "No thanks, I might get wet in the rain". In fact, IF ANYBODY HAS A MERCEDES 2011 THAT THEY WANT TO GIVE AWAY, please send me a private message and I will send you my mailing address. If the seats get wet when it rains hard, I don't mind suffering. :)

The whole idea of Gullwing door may have been flawed earlier on for the reasons you mentioned, but chances are they came up with a way to stop you from getting wet in the pouring rain. If you look at the car below, it looks like you will not get much wetter than any car with normal doors.
