After travelling almost 1 & 1/2 miles down a major road at 75/80 mph I thought it may be time to remind my wife there were another 3 gears left in the box, she just looked at me & told me I was just taking the piss & the car was fine (with stereo turned up to 11!) We even got pulled over by the police one day because they were convinced she was drunk her driving was so bad. She came back negative-which was about the same as her driving skill tbh.
