The problem isn't the test.
Among the problems was the amount of available testing facilities. The tire manufacturers said that if they tested 24/7 - and nothing else - it would take 3 years. Some said they couldn't accomplish the task unless they sacrificed some R&D testing. Some said that by the time they completed the first round of testing, there would be new models to test and they would never catch up.
