technically, any car that parks there won't be emitting any emissions for 99% of the time they are in that spot..
i wish i would have gotten a pic of the electric car charging stations in 2 parking spots in front of the Wal Mart north of Austin, TX when i was down there last month.. they must have just added the chargers, because there were huge fresh oil stains in the parking spots.. but it was like 100 degrees and i just wanted to get into the AC to buy a few things so i didn't take a pic..
