Borders have three uses: 1) to keep people out 2) to keep people in 3) to be able to search/detain people without cause I've yet to see a border that I liked. In plenty of countries this now extends to a certain distance away from the border (sometimes surprisingly large), even when you are not actively crossing or have not crossed.
You need to travel more.
I spent two years driving from Alaska to Argentina through 17 countries with my Jeep. The border that gave me the most trouble? Coming into the US in Washington (off the ferry from Victoria, Canada)
Also, see "Long Way Round" where Ewan and Charlie ride motorbikes from London to NYC, "around" the earth. Which border gave them the most problems? You guessed it.
