This seems like a sensible but odd carveout. The law is essentially legalising e-scooters on shared paths, and bike lanes on roads with no more than 20km/h. The proposition does not allow them on footpaths, which you’d think would be the most relevant place. Personally, I’m surprised they wouldn’t allow them on footpaths but no more than 5 km/h in heavy pedestrian areas (anywhere a car would have to do 40 km/h or less), especially since you could potentially require shared e-scooters to enforce this speed with GPS.
I’d hold off on that until they have half a shot at enforcing the 16 part and basic safety. Seriously, require licenses for those motor vehicles. Someone I know had to give first aid when two teens crashed into a parked car and came out with asphalt grazes on their face. Luckily, one of them had a helmet!
I fear that scooter money and shitty government means someone will die before we get the laws we need to protect riders and those around them.
