In Seattle, many beautiful craftsman homes get this tiny little slot of a parking space, right off the main arterial. It requires some kind of superhuman telemetry to park your Outback at a sharp 45 degree angle, doing 20 mph in order not to hold up traffic.
Enter: Space Guides. It's a recycled plastic product that guides you into your space on rails. Like an automated car wash without the automation. Think Washington State Ferry docks. At the end, you get a gentle rubber stop to maximize parking spaces while keeping your car from scraping the underside on a cement curb.
