Plaintiff tripped over the rear wheel of a Bird electric scooter that the user had parked with its rear wheel protruding into a public sidewalk. The City of Los Angeles was not liable for failing to enforce conditions of its license which allowed Bird to operate in the city since the city exercised discretion in determining whether to enforce the license conditions. (Gov. Code 818.2, 818.4, 820.4, 821.) Bird, however, owed plaintiff a duty of care as injury from poorly parked scooters was easily foreseeable. That users parked the scooters in improper locations did not relieve Bird of liability for not insuring that its property–the scooters–were not left blocking public sidewalks, or if they were left, that Bird quickly removed them from those locations. Since Bird’s own conduct contributed to the accident, it could not avoid liability by blaming the concurrent negligence of its users. Bird’s duty of care included a duty to exercise care in not renting to users who it knew were likely to leave the scooters in dangerous locations and to make the scooters in ways that would make pedestrians notice and avoid them. Plaintiff also stated a private nuisance cause of action for having its property left on public sidewalks in a manner that obstructed safe passage.
