Are you sure about that? When I drove back from Ashville once at 2am I had the cruise controll set a 90mph the whole way back.
Hmmm...looking at your profile you're driving a 2.5RS...I'm talking about the WRX. Maybe it's different? I remember reading something about the 80mph speed limit on this site, plus when I tried in mine I kept pressing the accel botton but it never went beyond 80.
