The term 'road menace' refers to a person who is a danger to other drivers on the road. Two possible solutions for this term are 'speeder' and 'speeddemon'. A 'speeder' is someone who drives at excessive speeds, often above the speed limit, and is a danger to other drivers. A 'speeddemon' is someone who not only drives at excessive speeds, but also engages in dangerous driving behaviors such as weaving in and out of traffic, tailgating, and running red lights. Both speeders and speeddemons are considered road menaces and can cause serious accidents.
