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.
Keep as many e-scooters, e-bikes, e-whatevers off the walking paths. They’re for walking, not swarms of scooters weaving through pedestrians.
Some jackass kid almost ran over a toddler in the walking path at a local park near me when I was last there. Kid riding it was nowhere near 16. Why parents think it’s Ok to give their kids essentially a motorcycle to drive around with no license is beyond me.
