Hi Raam!
You someday wrote that it’s silly to wash cars and every time a though to wash my cars comes to me it simultaneously reminds me your entry.

I write to say that it’s not so silly how it could appear if you do not drive a car.
Yes, rain washes away a certain percent of dirt but nevertheless the car is not clean.
I agree that absolutely clean car are not needed (only wanted) but if a car is so dirty that it could make you or your passengers dirty too… it’s time to wash it.
And sometimes it happens even at rainy period.
