LOL, reminds me of a similar story .... years ago my wife was driving home from a wedding at a small rural hall since I had a bit much to drink. Our car at the time had an electronic dash which could display metric (kilometers) or imperial (miles) at a push of a button. After a few miles she started to complain that the car was handling poorly and difficult to drive at the speed limit of 100 km. I looked over and discovered that the dash was displaying 102 MPH.
It was dark and I was half asleep so I didn't notice anything until then ... scared the shit out of me. Didn't know that pontiac could go that fast. :redface:
