I believe the issue was that half of them would have had to be back to the direction of travel, meaning potential back/neck injuries in an accident. The Stagecoach Megabus sleeper coaches used to have staff checking you were the "right way round" to avoid this.
I'm not sure transverse pods would have been very nice - no opportunity to look out of the window.
Personally, I think they should have done couchettes - either transverse or longitudinal. (A proper couchette would allow it to be used either way round).
You’re making that statement based on zero knowledge of the facts. The “crashworthiness issues” of the lie-flat pods were much discussed here a wee while back but as far as I saw no one ever produced any tangible evidence that this was a factor in why they were not progressed. Many people stated it as a fact but no evidence ever emerged in the public domain. It could easily have been an entirely commercially driven decision for all we know.
I'm not saying you're wrong, especially since I know nothing about it at all, but that does seem a bit daft to me. All trains have seats which face backwards, and surely if you're lying down/reclining it makes even less difference which way around you are?
Personally, and knowing at least a bit about airlines, I think the commercial viability of ‘pods’ would, in reality, have been slightly lower than a snake’s belly.
It doesn’t surprise me for a second that they were not pursued.
My only doubt about whether commercial reality is something that Caledonian Sleeper has fully-grasped, is some of their continuing blindness in terms of what it will take to deliver a service that meets the expectations of their supposed (new) target audience.
