Also coal powerplants run much more efficiently than a car engine.

  Is there a statistical report on this? I'm not contesting your claim, I'm just curious to see _how_ much more efficient.

  Internal combustion engines operate at about 25% efficiency (per this paper, page 54) https://deepblue.lib.umich.edu/bitstream/handle/2027.42/57640/mpapke_1.pdf?sequence=2&isAllowed=y https://deepblue.lib.umich.edu/bitstream/handle/2027.42/5764... Coal power plants operate in the range of 34% efficiency https://www.eia.gov/tools/faqs/faq.php?id=107&t=3 https://www.eia.gov/tools/faqs/faq.php?id=107&t=3 https://www.eia.gov/electricity/annual/html/epa_08_02.html https://www.eia.gov/electricity/annual/html/epa_08_02.html

    Also they tend to be run very far away so you aren't getting a blast of pollution to the face every time you go outside

    I wonder how much of that gets offset by transmission loss and the scooter's charging/discharging inefficiencies? Not that that would be a reason not to use scooters in and off itself, since they're be posed to take advantage of grids that will hopefully become more and more renewable over time
