Actually I'd disagree, you're at the least putting pedestrians at risk (there have been cases of people being badly hurt by having a bicyclist collide with them, let alone a moped going along at max speed) And there have been fatal car accidents where a person has hit a motorcycle/bicyclist and then gone out of control. Mopeds being somewhat more rare on the road in most areas, you're just less likely to find articles quoting that.
One quote... from the BBC website
"A cyclist, who had drank a litre of fortified wine, knocked down and seriously injured a pedestrian in Manchester. Last summer, he was given a nine-month prison sentence. "
