Most Dangerous thing in Houston.

To me the most DANGEROUS thing in Houston is discourteous ignorant pickup truck drivers. They drive like they're going to receive an inheritance, without thought or care for anyone in their way. I was cleaning the windshield on the passenger side of my car when a truck drove in next to me like it was coming in for a pit stop. I remember when driving a pickup truck was a big responsibility because it was bigger and more dangerous, so you drove slowly and carefully. I don't know how to attack this problem. But it seems as if nobody's gone to classes on driving.
