You see, we made the decision to make the doors and the roof of the Typ-I much, much stronger than what's specified by law for a passenger vehicle. We want the Typ-I t be renowned not only for its remarkable performance and efficiency, but its safety too. One of the ways we've done that is to look at the federal safety regulations and ask not how we meet them, but how do we *beat* them, and beat them by a comfortable margin. To do that, we need to test and inspect a variety of different manufacturing conditions and materials. And thus, we've built a testing lab in house just for that purpose, and we're constantly expanding our safety and testing team.
