I assume you mean electric unicycle?

I can't imagine delivering food on a regular unicycle - it's a lot of work.

The linked article was from 2007. He was definitely talking about a regular unicycle, and I doubt speed was a factor. The "unsafe" perception from others would be from the inherent wobbling associated with someone learning how to ride - it takes a while to get really smooth.

Electric or non electric does not matter.

And why would you put "unsafe" into quotes? Person who falls from unicycle is heavy, and can injure themselfs or another person.
