The main disadvantage IMO is that if you crash you're going to land flat on your face.
I have one of those 'funny' interview stories where the candidate turned-up with large scrapes all over his face attributed to falling off a scooter which suggests your data-point-of-one is contradicted by my data-point-of-one.
Most people try to regain control and straiten their legs when in fact you have to abandon it and bend your knees. Less height, less pain.
Small injuries happen more often than on a bicycle by a margin
If I get a scratch I get a scratch, I'll trade that for a shorter commute
What I really care about are real injuries. Those are from drivers and they are the same whether you're on a bike or anything else
