Why Can't I???

Chalk this question up to being stubbornly curious :roll:

O.K., I know what the manual says about the removing the skirts before sending the Insight through the automated car wash, but my question is why? I know, I know...it may cause damage, but how?

It seems to me, the brushes that clean the wheels would just pass over the skirts....What am I missing???

I know most of you will suggest hand washing instead, but for reasons I'd rather not get into :roll:, I'd like to send the car through the car wash with minimal effort...O.K. if you must know, I'm a lazy a$$...

Thanks for the info!
