They said "Even if you use environmentally friendly soap, or no soap, the water coming of the car isn't exactly clean."

If the rain is falling on your car it will have the same issue, no?

Not really something you can reasonably address.

I disagree, you can address it by keeping your car cleaned regularly at a car washing business that filters and recycles wash water.

Meh, there's a big gap in your problem/solution - driving in rain.

If you're cleaning it regularly then the rain won't wash off very many pollutants.
