Decidedly Off Topic, but here goes: What Nader complained about and what inspired his famous book, Unsafe at Any Speed, was driven (literally) by a trick driver employed by Ford who drove the car in a special way, (yanking the wheel to the left hard after hitting the brake hard to lose adhesion) so that the Corvair went into a 'four-wheel drift' on video. A classic spin-out, aided by the Corvair's tail-heavy, rear engine placement and stiffer roll resistant rear suspension. If you can do it right, and the car has a sufficiently low C of G, you can use such a manoeuver to stop the car fast. I used to do it all the time in a Mercedes Benz, and once to stop a Dodge from 100 mph in perhaps 150 feet. Some cars will roll if adhesion does not break in both wheels evenly. Rolling in a small car could be dangerous as your head hits the side window easily with violent rocking motion. The Corvair had a roll axis that descended rear to front, with more roll on the front than the back. This leads to oversteer and spin-out from the extra side pressure on the rear load tire.

What was needed out of the box was to make the suspension independent, and the front much stiffer (anti sway-bars), and the rear softer. If the car suspension rolled evenly, more weight was put on the front, and radial tires used to increase roll, then the car would handle normally, as the later 67 designs and the mid engine Spyder proved. The Ford Mustang was not much of an improvement in cornering on the later Monza designs. I could easily outcorner the 67-71 Mustang on torturous race tracks with a Mercedes using pirelli cinturatos. Probably stiffening the front suspension, and putting heavy luggage in the front would have made the Corvair behave normally under most circumstances.

The Ford-made Video was a classic early case of negative advertising, to hit the competitor below the belt. Nader was their 'unwitting' accomplice. The sales failure of the Corvair for which they credited Nader's book, inspired GM to embark on a program to get all the possible future safety devices under patent and then campaign the government to get them mandated. They wanted to put the shoe on the other foot so that the competitors would have difficulty meeting safety regs as they would have to pay GM to meet the requirements.
