As far as dockless last-mile transport goes, I'm actually a big fan of those electric kick scooters... but I acknowledge I'm an imbecile and they're really dangerous.

One issue I have with that model in general is that for many of the distances I'd like to use a share bike or scooter, it would take longer and cost money to walk to the vehicle and unlock it. It's frequently faster and free just to walk to my final destination.
