For a big city, the drawbacks of a Tesla police car would likely outweigh the positives, but Atherton has a solid case. The small town (they don't even have a grocery store) doesn't need police cars to cover huge distances, the Model S is also RWD and made in America, things police forces like. But most important, the combination of the quiet drivetrain and the fact that it's such a common vehicle there already gives it an enormous stealth advantage over any other car. And then, of course, there is the fact that Atherton has so much money that price really isn't an issue for them.
