Personally, I believe this doesn’t go far enough. For maximum safety, clothing should be banned, and body-cavity searches mandatory, for all mass-transit. Passengers should also be incapacitated to prevent possible physical violence, stuffed into sterilized Safety-Bags(tm) equipped with breathing apparatus, and inserted into Safety-Compartments(tm) in lieu of seats. This would also solve that pesky problem of passenger accommodation; sleeping passengers stacked like cord-wood increase profits!
Yeah! That’s the ticket!
