Mary from Eagan wants to know: Why do speedometers go so high? Her Honda CRV says 140 mph, but she, like many of us, would never go that fast. According to Larry Dominique, a longtime automotive engineer and current president of ALG, there are two reasons: 1) Consumer research shows that when people are driving on the highway, they like their speedometers to be between 11 and 1, like on a clock. That makes the needle easier to see at highway speeds. 2) Consumers believe that a car that says it can go 140 mph is better than a car that says it can go 120 mph.
