They did say 'calculation' which may cover what was simply a made up statement. As far as the breaks dying, Tesla said the power breaks stopped working because of a fuse with one of the two cars they gave them to test. They said this doesn't prevent the car from being drivable at all (since it has to pass breaks standards with the power breaks and without) and at no point did the car have to be pushed into a garage for any reason. Telsa also said neither car was reduced beyond 75% power. I think the show was dishonest with how they represented the test and considering Tesla was a new company struggling to do something different and do it well it was a nasty thing to do.
