If you're learning with no guidance or your wheel is buggy you may fall down a couple of times but it's mostly very mild since you just jump off. Some injuries can happen if you get cocky and not careful but I've fallen down 3 times already (1.5 years experience) and the worst I got was slightly damaged skin on my hands.

I've been cycling in London and I have to do unexpected hard breaks daily; pedestrians walk of the pavement without looking around, fellow cyclist makes unexpected move, etc. If the vehicle can't hard break and you just jump off, how can you avoid to hurt others?
I'm more worried about in the event of a vehicle collision. I had an EcoReco scooter for a time. A vehicle turned in front of me, I ran into it. It would have been much worse for me if the handlebar had not collided with the car first.
