San Diego has lots of dockless scooters and bikes, but at this year's Comic-Con, they're causing a disaster.

Scooters or bikes that riders can pick up on the street and rent using a companion app are a fun idea. They allow for a faster way to get to a destination that's a bit too long of a walk yet not long enough to justify hailing a cab. But they're now so easy to pick up that plenty of people who clearly shouldn't be grabbing the scooters and bikes are taking them for a ride and leaving them wherever they want.
