I disagree, and I agree with Rob. I've driven over 20,000 actual track miles on my cars, and I have never had a stud break.
I torque my lug nuts myself using an accurate manual torque wrench.

Not necessarily. A lot of shops use an air wrench without a torque bit, and do it by "feel". They may wind up with a proper amount of torque (80 ft lbs) but there's no way to be sure unless you manually torque them yourself.
Advice: Buy a good torque wrench and always torque your lug nuts yourself.
