On a tangential note, I don't why paved outdoor parking lots are built[1]. It seems to be an entirely pointless exercise in aesthetics to me. I've parked on unpaved spots (in large parks near hiking trails, etc), and never had an issue.

We really should have more unpaved outdoor that is simply trimmed semi-regularly if or when the plant growth gets too big.

[1] Unless you're in a sandy or snowy area, where shoveling the sand or snow is difficult on an unpaved surface.
