What increments does your speedometer have?
My nice old car has speed increments every 10 MPH, and even has a handy 55 MPH mark.
I've noticed that many newer cars have these increments in 20 MPH.
What does yours have? And what year is your car?
And why the heck did they start doing this in the first place, besides to save paint? I think I'd be annoyed having to try to do quick mental math at cruising speeds - seems like it would be pretty distracting.
