I'm on Oahu and there's probably way more traffic than you realize. The other day I drove from the Waikiki area to my house in rush hour traffic, a distance of 26 miles, and it took an hour and a half.

And as far as the all weather mats, they'd be great if you go to the beach a lot to catch the sand. I don't plan on taking my TCH on a beach trip for a long time...can you imagine, wet swimsuits on the seats, sand all over...no way!!
