Rhoades Car makes bikes that can drive like a car. It also has 4 wheels! On their website you can submit a free brochure request that includes information and pricing for their models. The Rhoades Car is available in 1, 2, & 4 seat models and can cost from about $1000 to $2000. The bike comes with a really comfy seat and is said to be easier to pedal than a traditional bicycle. In a two person model, either one or both can pedal the 36 speed gears. There is also an electric option and gives continuous pedal assistance up to 18 mph and can take you up to a distance of 30 or 60 miles, depending on which type of battery you get.
A nice alternative to taking your car short distances.
