It is fun. I’ve been behind the wheel of ‘em a few times, and it’s certainly a whole lot better than wrastling things around by “the Armstrong Method”, but you’ve got to know what you’re doing, and keep aware of your situation at all times. A moment of inattention or a careless misjudgment is all it takes to get yourself or somebody else fatally wounded or seriesly killed.
The few times I’ve seen one at work, I’ve noted the operator seems to be almost “one with the machine.”
I suspect it’s akin to trying to dance with a car as a partner.
