re: A pressurized Moon rover with spacesuits outside!
It looks like it might be a two man operation to get in and out of the suit, one person on the inside of the rover.
So if it is a one man operation and the automatic controls don't work to open up the back of the suit I guess you just have to jetison the other suit and try that port?
I think the original moon rover with it's "lawn chairs" and open to the enviroment design with the Astronauts always in their suits is the most efficient and light weight design and therefore the most practical.
Every gram of weight counts.
