How many deaths have they caused? How do those stats compare to the deaths caused by motor vehicles? Which one is more dangerous based on that data?

I have looked at local pedestrian casualty statistics and motor vehicles are by far the largest cause of injury and death in the large city where I live. I haven't even been able to find what was the last time that a cyclist or e-scooter rider killed a pedestrian. Meanwhile, cars and trucks have killed four cyclists this year alone.

this is bullshit, cars kill and injure orders of magnitude more people in Europe than scooters do. That's not to say there's 0 issues with scooters, because there are, but focus should remain on cars, not scooters.
