Yea I've never seen anyone riding with a helmet on these scooters. U see them all over south park bear the ball park.

I've rode a personal electric scooter for over a year now and I can say a helmet is a must. The biggest dangers I've seen is clueless uber/ lyft drivers cutting you off (happens a lot) and pot holes / cracks in the pavement. They travel at 10+ mph so if you hit a big enough pot hole your going to eat it.
