I agree that getting a speed display up and out of the instrument panel works particularly well for track cars (at least for drivers at the intermediate level). Easy occasional reference is fine. But I'm a little concerned that people might start seeing a little red mist shooting for new personal best speeds and be a little too intent on watching the mph's climb instead of the approach of their braking point if the speed monitoring is centrally positioned.I have it on my 2016 Denali and really like it I think it should be available on all track cars as I think it would work well at high speeds on a track.
