After a weekend trip here is what I found. Most of them were already known but it keeps happening.
Always the other lanes go fast. This is true especially when the traffic is moving slow.
You will see the sign for your exit just when you are at the exit and when you are in the left lane. (For some reason in New Jersey I seem to find all the route names just above the exit with no pre-warning).
There will always be a car in the blind spot.
Someone with the brightest possible light will be behind you.
You will run out of gas near the costliest gas station.
There will be a slow car in front of you within a minute you are on cruise.
The sign you have to read will be in front of a truck.
You will get lost only in the last part of the trip in local roads for which you will not have maps.
