You realize that the speedometer is not angled towards the driver right...? So you're looking at the speedometer from a lower point of view, aka the needle looks to be higher than it is. You have to lift your head to the right to look at the speedometer straight on.
I have noticed the angle thing too. I found myself getting passed by people constantly when driving around town doing what I thought was 35, but was really like 31-32. I wish you could angle the gauges down like in a 370Z.
Nah, it wasn't that. I took a picture of it and now I am looking at the picture, what happened was I thought the line before 40 was 35 (and digital one was showing 30), now I see that is not the case. I was just too tired today:(
