Tesla thinks you will be just fine without the ole ‘break-and-roll’ test

Not sure what “brake-and-roll” testing entails… but it sounds important. It sounded important to investors, as well because Tesla stock dropped more than 7% after discovering the company decided to skip that particular test on its Model 3 cars.
The test is redundant… according to Tesla. The company did manage to meet its goal of producing 5,000 Model 3 cars in just one week. However, many are wondering if the suspended test is redundant or if it was removed to help the company speed up production.
Your brakes will probably work… because every car built still goes through brake tests, according to Tesla. They also want you to know that all vehicles have their brakes and alignment tested before leaving the factory. So the brakes are good – try to avoid the rolling part.
