Hagerty are running a nice story, on the ramp-to-ramp spiral jump, 50th anniversary. The stunt was developed as part of validating a detailed math model for car accident reconstruction--including early computer graphics. After touring for several years as part of an auto thrill show, the stunt was eventually featured in the James Bond movie, The Man With the Golden Gun. The article also details a couple of recent copies of this stunt.

Your submitter knows someone that insures a classic car with Hagerty, but has no other connection with this specialized insurance company.

    From memories, the stunt drivers call that "high-ski" (sp?). Once the car is balanced up on two wheels (that is the hard part--the cop car continues rolling and rolls over), it's similar to balancing a heavy motorcycle. Because the response time in roll (inverted pendulum) is slow, it takes some practice to work out how to maintain balance and also follow the desired path. And of course you have to switch your mental/internal control strategy from 4-wheeler to 2-wheeler.

    I've done something like this with a small motorcycle sidecar rig -- start out on three wheels, then turn sharply to pick up the sidecar wheel and ride the motorcycle on two wheels, but at a large lean angle to balance the offset weight of the sidecar.

    The same hell driver's show that toured with the Astro Spiral Jump in the 1970s also performed this stunt around the country.
