There are a few rules of the road. Most of them are defined in that manual you pick up at the DMV when you're 15 years old.
The others you learn as you go. There are a few of those "learn-as-you-go" ones that I deem very important. Here is one.
When you are driving 65mph on a parkway with a windshield resembling this:
please do not
a) Talk on your cell phone.
b) Play with your hair.
c) Come into my lane... especially when the lane on the other side of me is full of semi-truck.
I'd greatly appreciate if you follow this rule.
Especially if you're a blonde girl. Driving a Silver Jetta. Today. On Briley Parkway. Around 3:30pm.
