Some manufactures with obsolete 4 cyl gas engines use the car's stereo to cancel out some of the engine noise. Could Tesla use that tech to cancel out some of the only noise you hear, that of the tires? Studded tires roughen up the roads here in the PNW and generate lots of tire noise in any car. I am always amazed how quiet the roads are where studs are not used. Tesla has a camera in the cockpit, do they have a mike?
