We were on the way to TexMex last week and we had driven nonstop for about 1.5 hours and I look down and notice speedometer says 80 when I know I might be doing 60. So i start slowing down til it says 70. Meanwhile old ladies are passing me by so I'm going WTF. I pull over and come to complete stop and it says I'm going 30 MPH. The next morning when we drive it, it reads normal but i was wondering if this has happened to anyone and what might have caused it
