The vehicles, which are controlled via a remote button that determines the route and destination, are part of Daventry District Council's efforts to find 'personal rapid transit' alternatives to the traditional car.
The tests are part of a project by European Commission research group CityMobil, which aims to improve urban transport provision.
Daventry District Council leader Chris Millar told the BBC: "We can build lots more car parks and have lots more cars going in, or we can look at a viable alternative to the car. We believe this could be the answer."
The CyberCars are being demonstrated on a test track in Daventry until 5 October.
