Motor racing, especially Formula 1, is going to great lengths to make overtaking easier and avoid the usual high-speed processions which are hurting their TV ratings.

Today’s invention is to design all the cars around a similar rhombus-shaped plan, as shown.

This would reduce any sudden changes in flow cross section during the overtaking move, lessen the aerodynamic benefit of tailgating and thus greatly reduce the drag and buffeting when one car (yellow) attempts to pull out from behind to overtake another (red).
