I did that once on Metro Parkway going across Gratiot. Used to be a helluva crown on Gratiot there. Those cars were really quishy on the suspension and didn't handle for shit either. They were great comfy cruisers though....
the problem was that once the air got under the car, it basically ripped the hood off. If the car was streamlines and sealed top and bottom, it probably wouldve been slightly more successful
