"Now, the police department in Fremont, where Tesla’s main factory is located, is also going to use a Tesla Model S.They are being a little more tentative about the deployment of electric vehicles in their fleet than some other departments going electric.
While other police departments are deploying whole fleets of them, like the Basel police force modifying a fleet of 7 Tesla Model X vehicles into electric patrol vehicles, the Fremont Police Department bought a single used Model S and they plan to use the vehicle as part of a pilot program"
