Runabouts are vehicles designed for short trips, but they also go by other names. For instance, they are often referred to as roadsters, which is a term more commonly used for sports cars. Another synonym for runabouts is coupe, which typically refers to a two-door car with a fixed roof. Convertibles are also similar to runabouts, as they have a retractable roof that allows for open-air driving. Hatchbacks are yet another synonym for runabouts, as they are small cars with a rear hatch that provides access to the cargo area. Ultimately, runabouts, roadsters, coupes, convertibles, and hatchbacks are all types of vehicles that are optimized for short trips and small loads.
