Absolutely. I don't have a problem with most scooter owners, but here in a city with a lot of tourism, the rental scooters are often a menace. I was waiting outside of a restaurant and took half a step back to let some people through. I brushed against something moving fast, and it was some tall yahoo going downhill at max speed on a scooter. If I'd taken a full step back, somebody would have needed medical treatment.
Learning how to ride one of those in a city takes time, practice, and thought. Which you will surely get if you buy one. But apparently not so for the rentals.
