Rush hour traffic

Why is it that people know that the traffic is heavy during "rush hour" periods yet they still continue to join the many who ply the streets?

1. To be in the "in" crowd. To belong, you must be there for may lose the concept of the rush hour traffic if we let it die away.

2. Work place. All offices end work at 5:00pm. Why linger in the office when join can join the mob gathered in the streets and crammed in buses and trains?

3. Normalcy. Rush hour is normal. Why avoid it when everybody else are in it?

4. Economy. Most pubs, bars, restaurants, and places of ill-refute offer special promotions and reduced prices during "happy hour" which is another term for rush hour. Like the question in item number 2 - why spend your time in the office when you can spend it getting drunk?

5. Time table. Why go home later when you can go home now?

And once everyone is home they will say, "I had a rough day" when they have only spent a few hours in heavy stressful traffic.
