If you abandon a car in the middle of the road across two lanes, you'll fairly likely see relatively hefty fines, possibly lose your car. This hurts you, the abandoning party directly.
If you abandon a rental e-scooter in the same way, you'll most likely have no repercussions, and at worst the cheap e-scooter is forfeit which doesn't impact you, the abandoning party at all, and not really the e-scooter company either since they're most likely on a VC funded mission to try to flood the market with cheap e-scooter rentals until the competition drowns.
There's some seriously skewed incentives at the root of the rental e-scooter plague.
