All of the commenters saying e-scooters shouldn't be allowed on sidewalks are right. Sidewalks in most densely populated US cities are too narrow and busy to safely allow a human gliding along at 15 mph within ~2 ft of a doorway where another human may be exiting, or past blind corners.

The bigger issue is that e-scooter parking is fundamentally broken right now. Despite being told not to, users still park them in the middle of a pedestrian walkway. Even if the user parks them correctly, they get knocked over or blow over into the walkway. This product is broken until these companies do what Jump did, and INTEGRATE A LOCK INTO THE PRODUCT, and make users lock it to something at the end of their ride. This almost entirely eliminates the problem of blocking a walkway, and also reduces the loss of product to theft, accidental damage, etc.

Since they're required by law in California, I'd also like helmets to be integrated into the locking mechanism, but that's a nice-to-have.

E-scooter companies: Build locks into your products. It fixes many of your problems.

Now also imagine the drone hit the windscreen, and not the wing. Or went into the prop / engine. Or hit the tail and damaged the rudder.

The leading edge of the wing is likely the best case scenario. All others probably result in far more serious consequences.

Yes.

Copenhagen is one of the most wonderful cities to get around I've seen. Many of the bike lanes are separated and raised from vehicle street level by a small curb, which does not stop a determined vehicle (or out of control vehicle) from invading the lane, but does wonders for the psyche of the bicyclist. The feeling of gliding through the city via your own network of paths is incredible. There's often plenty of bike parking too.

In my opinion, all densely populated cities with reasonable climates should be built that way. If San Francisco had similar dedicated lanes throughout the city, and more bike parking, I'd absolutely wager that car ownership (and all of those cars laying fallow on the street) would drop significantly.
