Re: Windshield wiper/headlight suggestion...
What I consider dangerous are the headlight settings which allow daytime running lights to be on, but do not turn on the rear lights of the vehicle. So many people are driving around oblivious that they cannot be seen from the rear when it is rainy/foggy, or semi-dark.
