I agree floor mats should be standard but not the ones they sell in the store. We should be able to choose to get the car delivered with either good quality textile mats (like they sell separately) or all-weather rubber mats. This should be configurable at ordering time, like the rest of the interior.
I do not want texile mats at all, having the car delivered with such mats will only increase the amount of crap I have stored permanently in the attic...
My Leaf came with rubber mats only, like most every other car sold in Norway.
