Everyone talks about losing structural rigidity. But no one offers any numbers. These buses are built way beyond acceptable limits. You can remove 25% of the structural ability and still be in the needed safe zone. Is more better, in some cases yes. Is less bad, not allows, often more than enough.

With the millions of buses out there, how often do you see a bus rolled over? I would hate living my life off of "what if's" when that what if is highly unlikely to happen at all.
