Who said they won't stop or turn? I didn't.
I said they won't stop or turn nearly as well, and that's absolutely true. Believe it or not I have driven these cars with stock torsion bars and 14" or 15" rims with the standard choices for all season hockey pucks for tires. Compared to how my car is set up now the handling and stopping capability was pathetic. I have run everything from .85" bars up to 1.12", and until you get up to about 1" bars the handling is very sad. So yeah, I have no problems saying /6 bars on the street with radial tires negatively effect your handling and stopping. They absolutely do.
I'm also gonna go out on a limb and say that "most everyone you know" probably drive their cars less than a few thousand miles per year, and only in good weather conditions. So it's not really surprising they're not crashing on a regular basis. They barely drive at all and usually only under the best conditions. That doesn't prove their cars handle or stop well.
