Here is something I’d use all the time. In 2007, Opel will launch the Flex-Fix system as an option on its Antara and Corsa models. The system is a retractable two bike rack that slides in-and-out of the bumper.
It’s completely concealed and allows users to avoid strapping those bitchy straps everywhere. This needs to be an option on US cars immediately. Write your congress people, or something.
