Been a long time and the link is lost but I saw a California DOT study that had Italian style scooters as dangerous as bicycles. It's at odds with what motorcyclists think. Also at odds the risk from motorcycles goes up sharply with displacement.

My personal experience was all dismounts from bicycles lead to bruises if that. And friends crashing at high speed tend to end up with hand and wrist injuries. Flip side I have three friends that needed knee surgery after stand up scooter accidents.

So I agree the typical dismount is really important.
