No they aren't. Poor safety leads to economic damage. A collision can delay thousands of people.

Note that a few dozen terabytes is also nothing. 12 TiB is about $800 on an SSD and about $250 on a HDD. Plus some overhead for the enclosure and redundancy, of course. It costs on the order of a day's pay for an engineer, at most.

I don't excuse wanton waste of storage because it's easy for sloppy practices to balloon to massive confusion and inefficiency. But that discipline should be enforced by good engineering practices, not by limiting resources.
