Snoking, you said it, if the person working the awning is dumb enough to place the lock paw lever in the roll out position and then drive away, then yes it can blow out. BUT, if you leave the lock lever in the roll up position and the awning isn't damaged it's not coming out. As far as the rivets go, if they are misaligned then the awning has already been damaged and needs to be repaired or replaced.
If you would like to test this, with your awning ready for travel, get you and a friend at each end of your awning and try to pull it out.
