And really, the tired business executive is the ideal customer ... but you're probably more likely to get a bunch of less-than-ideal customers whose actions inside the pod are going to require a more extensive cleanup.
I have a feeling that even if the company has come up with some innovative ways to address these problems, I'm pretty sure the public perception of the pods will be negative, because you're naturally going to assume that the pods have been occupied by people doing unsavory things. It's going to be perceived as the generally gross Porta-Potty of the accommodations industry.
One of the nice things about hotels and hostels and other places that are staffed 24/7 is that if someone lights up a cigarette in a nonsmoking room, or starts trashing the hotel room, there's someone on hand to address the problem. Here, I can only assume, the pods would only be sporadically monitored.
I think a better solution to problem of tired executives with minimal needs for amenities is in the pod hotels that you can find in the biggest metro areas. They're somewhat similar to these pods in design, but because they're located in hotel structures, they are staffed and the linens are changed, rooms cleaned, etc. by humans:
