I agree. I've ridden many times on a
scooter, and it does seem like the cabin exiting the ADA area comes close to colliding with the cabin making the turnaround on some trips. I don't know whether that's actually what's causing the shutdowns, but it would seem prudent to have the departing cabin start a few seconds later.
It sounds like your cabin may have had a bad battery. The batteries are supposed to be charged every time the cabin moves thru a station. I think there's an light on the outside of the cabin that indicates whether or not the battery has power. I don't know whether cm's are checking that indicator before they load each cabin.
It's not Disney's job to make it work. It's Doppelmayr's.
That's a silly analogy. Jetliner cockpits are not public accommodations.
