They need to generate some real test data similar to Consumer reports using a dyno for rolling resistance, and have some experts drive them on a closed course for sport driving comparison. Forget this "seat of the pants" testing.
We were in a controlled environment -- Bridgestone's test track outside Rome, Italy. While I would have enjoyed flogging the tires in the real world, they kept us on a very short leash at the facility. We did drive up into the mountains outside the gates, but (again) they had us playing lead-follow with a pace car.

The 3G (third-generation) tires still have not been released to the public.
