In Portugal, e-scooters had to be severely regulated as many gruesome and bloody accidents happened because their users entered high speed ways, heavily modified the scooters to achieve over 80km/h speeds, were left abandoned by users of rental services everywhere, invaded sidewalks and endangered pedestrians or public transports lanes.
The ever growing size of cars is a worthy cause of worry: I drive a Ford Ranger for professional reasons and the vehicle is ridiculously cumbersome, wide and clumsy for the roads I have to use. Lawmakers need to cull the auto makers arms race on bulky vehicles.
But lets not overlook that e-scooters are a very big source of traffic accidents by themselves and let this micromobility solution run amok.
