Driving many miles??

Over the course of the last month I have driven many miles. Total since Feburary 24 I have driven over 2700 miles. In the time I have covered the states of Indiana, Illionios, Missouri, Arkansas, Tennessee, Mississippi, Alabama, Georgia, South Carolina, and North Carolina. Two different times driving from my house just north of little Graysville, In to Indianapolis, In which is about a 100 mile trip. During these long drives a person tends to realize some things that normally one does not see. Here are just a few of the great visions of learning I have had:

1. It is possible to eat a sandwhich with two hands while driving 80 MPH
2. After the first 4 hours of driving your voice will start to become hoarse
3. It is possible to go 620 miles in 8 1/2 hours
4. One can drink 2 bottles of Mountain Dew and not take a bathroom break
5. Jackson, Ms is the only town that requires all gas to be prepaid
6. You can go 3000 miles over your due oil change
7. You can watch T.V. from another persons car if you drive close enough behind them
8. Everyone looks at you as you pass them on the left, but only about half look when you pass them on the right
10. More cops patrol the southern 50 miles of I-57 than any other stretch of interstate
11. The sportier the car the slower they will drive
12. 50% of people are on their cell phone while driving

This is by no means an exhaustive list and you might want to add some of your own. I don't understand some of these but maybe you do. Can you help me understand?
