Ah, that's a neat movie. I don't know why it isn't on the front page of their website.
Still, the fact that they've got it working once doesn't mean the problem is solved. You need it to work all the time, in all sorts of weather conditions, and automatically stow itself if conditions become unsafe. Failure means plowing into the ground, which is probably going to be expensive each time it happens.
I'm sure they'll never get the plow-into-the-ground rate down to zero, but there's gotta be a lot of work still to be done to get it as small as possible.
