This happened to me today:
Apparently my Segway Mini has a wicked sense of humor.
Moved completely on his own to block the door and lock me inside. Was almost perfectly perpendicular and impossible to slide the wheels sideways to open the door it was just folding the door like a taco!
At first I had no idea whatever the cause of the door being locked but though the 1" gap in the bent door i noticed Ninebot was not where i left him!
Praise Jesus i had Bluetooth remote on my phone to drive him away from the door as nobody was within 100s of feet I'd still be in there!
Funniest thing that I've witnessed forst hand this year!
