If it illegal, why then do
If it illegal, why then do auto manufacturers offer a defeat switch on the dash for such purpose? The new Ford Ranger that just came out, well it has an automatic defeat for the stop/start when the truck is in 4 wheel-drive mode or when pulling a trailer....per Ford's own add copy. It is a gimmick for two reasons: 1) When a vehicle isn't running it produces no emissions, and 2) It uses no gas, which refers us back to reason 1.
