A contraction of Motorist and Retard - A motorist who mistakenly believes that they have exclusive rights to get to their destination in the fastest possible way. Everyone and anything that impedes them (including slower moving trucks & busses, congested traffic, cyclists, pedestrians and traffic controls such as traffic lights and stop signs) are all legitimate targets for irrational hatred, verbal abuse and physical rage. The Motard! is always ranked in the lowest IQ quartile, victims of the Dunning Kruger effect and can be easily identified off road by their distinctive atrocious spelling and complete absence of anything resembling grammar.
Hey, look at that motard! trying to run people off the road.
The motard! said "cyclist don't pay rego, they should be banned from my roads"
