Designer Carl Archambeault's 'Scarab' is a self-driven police car for high speed chases. In other words, Scarab is a real-life K.I.T.T. from Knight Rider -- but without David Hasselhoff behind the wheel.

The car is an electric robot chase assistant to lower the number of Police casualities in high speed chases. Scarab is lightweight and emission-free vehicle that sits ideal beside a patrol car. Whenever a speeding vehicle is detected, the officer tags the speeding car with a radar gun and passes it on to Scarab to chase.

This chase automobile has no weapons, but there could be possibilities to equip it with an EMP or signal jamming device.
