San Francisco has banned commercial electric scooters, which can be rented via apps, from its streets – after several months of confrontation between the authorities and tech companies.

Three upstarts – Bird, LimeBike, and Spin – that have littered the American city with thousands of scooters that can be grabbed, used, and then left anywhere, now face fines of $100 per day for every scooter that is left in a public right of way. In recent weeks, the council has seized and impounded literally hundreds of scooters abandoned illegally.
