One gets good videos on the elevator. And, the people around the E-Scooters are largely trapped.
Those videos appear to be E-Scooters. Why aren't they left in the parking garage? My guess they are being moved around the building under power, rather than being pushed by hand.
Is there something in the lower rear right hand side of the E-Scooters that makes them vulnerable if bumped?
Ok, watching the IndiaTimes video, I'm not convinced it is the E-Scooter that went up in flames. It appears as if the second person in the elevator set a briefcase down near the rear of the bike. I think it may have been the briefcase that burst into flames (laptop powered on inside the briefcase?).
The cause of the fire in the YouTube video is less clear.
Of course the E-Scooters make the electrical fires much worse.
Anyway, the impact of the elevators may be in part bringing multiple electronic devices together (as appears to be the fault with the IndiaTimes video).
