The exit road at the BMW Performance Center parking lot in Spartanburg, South Carolina, was narrow and dotted with tightly spaced orange cones. I carefully guided the 5.5-metre (215.5 inches) long Rolls-Royce Spectre out of this lot before turning onto the highway entry ramp. I sat near the rear axle, with an expansive hood stretching ahead of me. The Spirit of Ecstasy figurine stood at the car’s distant front end.
