Randy, the above is pertinent to the 60 - 64 Corvairs with swing axles. An extreme oversteer condition would cause the slide side axle to tuck under, usually due to under inflated tires, and essentially "trip" the car, causing a rollover. One of my friends' older sister was killed in a Corvair ( a 61) rollover resulting from a quick steer to a avoid a deer in the road.

For 65 and up, that problem was eliminated by changing to double jointed half shafts, with trailing arms that kept the rear wheels parallel in their range of up and down movement.

The persistence of reports of bad handling traits in the earlier models is what eventually killed the market for Corvairs, even though the problem had been fixed.
