You spend enough time on the road you start thinking of the strangest things.
Like how long I have sat in the drivers seat of my current truck. It has about 155,000 miles on it and just to make it simple lets just say it was all at 60mph. That's ends up being 2583 hours. Divided by 24 hours equals almost 108 days sitting in the drivers seat.
Here is another. At 1750rpms the motor's crank will spin 105,000 an hour and after a 10 hour trip it will spin more then a million times.
If you take the 2583 hours and times it by 105,000 revolutions per hour my truck's crank has spun more then 271,215,000 times.
