> Scooter trips are more frequent, done by everyday people and should be banned on sidewalks. Someone should do a cost benefit analysis of danger to pedestrians from the level of cars on the road due to air pollution compared to the reduced harm from cars but increase in risk from scooters. Having cars drive by is non-0, exposure to break dust and car exhaust are known to case long term irreversible health effects, is there a crossover where a certain % of people getting hit by a scooter at 10mph is a net benefit if there is a large enough reduction in vehicle traffic? Of course tire particles still exist from some scooters, but the tire types are different and I also wonder what the rate of tire dust from the tires scooters use, and what the exposure impact is there. We tend to fear the immediate dangers we can see, but not bother doing the math on long term consequences.
