<VV> Nader

[Hugo Miller]

I watched a tv marathon the other night on the history of the motor car 
and in particular the 'Big Three' car makers. The Corvair got a mention, 
and they showed a clip of Ralph Nader making some specific and 
detrimental remarks about the Corvair's handling on camera. He said, 
inter alia, that the car could break away 'suddenly and unpredictably' 
in corners.
That statement, along with others in similar vein, demonstrably cost GM 
a great deal of money in lost sales. What I would like to know is why 
Nader wasn't sued. If I went on national tv and made specific claims 
which disparaged the products of a major corporation, I would expect to 
find myself walking out of court bankrupt in a very short space of time. 
Or was Nader actually able to substantiate his claims to the extent that 
would survive a libel suit?
My personal view is that there is a grain of truth in what he said, but 
that his claims were wildly over-stated, and demonstrably so. How did he 
get away with it?
