Similarly, I used to see these a lot last year, but I've only seen one person near me riding a one-wheel recently. Sadly, he was riding it with what looked like his 3 year old daughter holding on to his knees for dear life. I wanted to say something, but I assumed they're just going "to the store" nearby. But still... hurting yourself is one thing, but riding an e-scooter or one-wheel with young children seems like quite another...
