The uncertain rules about how to ride Bird's E-scooters – together with reckless driving habits and the scooters' high speeds – have led to thousands of accidents involving Bird's E-scooters. The risks of riding one of Bird's E-scooters are not hypothetical: Hospitals have noted a sharp rise in emergency room visits in the weeks after Bird dropped off a fleet of vehicles. These E-scooter accidents tend to fall inside one of the four following categories: 1) The accident only involved the driver of the Bird E-scooter, 2) The crash involved an E-scooter and a pedestrian, 3) The crash involved an E-scooter and a car, and 4) A pedestrian tripped and fell over a stationary E-scooter.
