A couple of months ago we flew into YVR and took a cab home. What the driver told us was very interesting, and I'm assuming it's true. He could take us to Vancouver but could not pick up in Vancouver and take somebody to the airport so he went back empty. Further, there are cabs that can take you to the airport from Vancouver but are not allowed to pick up there and have to return empty. So half the cabs are deadheading empty and then we complain that we can't get a cab when we need one. Dear God! If some evil genius had thought up a scheme to double the carbon dioxide we pump into the atmosphere, they could hardly do better than this. This is insane. How do we fix it?
