When we were there in July, our bus had stopped and a car was going to drive through without stopping - our bus driver laid on the horn, and practically jumped out the window gesturing to the car so it would stop. He wouldn't open the door until he was sure it was safe for us. I was impressed with the safety-mindedness of all of the drivers.
For the most part, the golf carts were also courteous, but there were some cars that should have slowed down. I was glad to be on the bike path when we didn't take the bus. We were able to ride our bikes all over FW with no problems.
