There aren't enough buttons, there is too much to read, and all of this while I'm driving.
I remember my friends dad had a Corvette or something in the mid-late 90s, and it had this red projected HUD on the windshield. All of your information was right at eye level, and you never had to look away from the road to see your RPM or speed, and probably more, but that was 30ish years ago, and I barely remember yesterday.
