Why Can't Drivers Stay In Their Own Lane?

Am I the only one who has a problem with drivers staying in their own lane. What is going on? Do cars have too many gadgets these days? Are cellphones the problem? I find myself in close calls almost every time I get behind the wheel.

Drivers having a hard time staying in their own lane is not just a Lafayette problem. Not just the South either. It's a nationwide problem. In the last 6 months, I've been to at least 4 metropolitan cities outside of Louisiana and the problem was prevalent in those cities as well.

In my rant tonight I site the problem, unfortunately, I'm not sure how we fix the problem.
