The Tesla Model S could be the ultra-fast police car you never hear coming — until it’s too late. At least, that’s what the city manager of the posh Silicon Valley town where the Model S is a top-seller says he wants. Tesla police cars! What will they think of next? You’ll recall Atherton, California as the town that ranks at the top of the list of America’s wealthiest zip codes. In Atherton, the average home costs $6.65 million. It’s also a place where the Model S is the top-selling vehicle.
