I find it amazing how many people do not turn on their lights when visibility is low. Not only when it is raining hard or in fog, but as it turns from daylight to dusk then darkness. The thing is, if their lights are not on, then their dash is not lit up either. That means they can't even see how fast they are going. You would think these people would realize it doesn't cost them a dime to turn on their lights. While the car is running it is not using up battery power. Makes it dangerous for all the rest of us.
