energy savings?

OK here's the question. Do people think they are saving energy by driving with just their parking lights on. Do they think that just because it is light enough for them to see that everyone can see you without any lights on. The color of a car makes all the difference in when another can see them in low light conditions. The law makes motorcycles have lights on all the time. Maybe cars should too. In the state of Missouri drivers are supposed to have head lights on 30 minutes before sunset and 30 minutes after dawn. It is also the law that if your wipers are on so should your head lights. Have you ever heard of anyone that got a ticket for those laws. Not me. I wonder how many accidents were caused because they didn't see each other.  Well consider this if you are one of these energy savings people.  Who knows, it could save your life or of someone you love.
