"He eyed and saw afar on Essex bridge a gay hat riding on a jauntingcar. It is. Again. Third time. Coincidence.
Jingling on supple rubbers it jaunted from the bridge to Ormond quay. Follow. Risk it. Go quick." (U11.302)

A Jaunting-car (or Outside Car) is a light two-wheeled carriage for a single horse. It usually seats four persons placed back to back, with the foot-boards projecting over the wheels.
