I disagree. Actual race tires will exhibit gradual, controllable, breakaway.
With race tires, it's a lot easier to get one end (or both) hung out, be
half sideways, and still control what's going on. Race tires will get very
sticky when warmed up - I've returned to the paddock area and have had gravel
from the access road stuck all over the tires.
Some of the street radials behave like you describe.
