Do you say thanks while driving?
As I drove to work this morning I let multiple people in on the very busy highway. Some people say thanks with a nice wave when you let them in (or out) or make whatever weird movement they're trying to make. Regardless of how you feel about letting people over (this is not a traffic question) we all need the help of other drivers at some point. How many of you say thanks when someone does something nice for you on the road?
