A speeder is a common personal flying vehicle. It is often described as a flying car.
Speeders are seen throughout San Francisco, such as the one owned by Tex Murphy. One can either drive a speeder manually, or simply enter a destination code and use the auto pilot.
With the increasing popularity of the vehicles, the American government implemented a "no-fly zone" between two countries, patrolled by armed drones. Thus the only safe way to cross a border was through checkpoints, where each speeder was scanned, searched, and cleared for passing through to another county.
