Yeah, you got me thinking twice about it. On reflection, I think the reason it didn't sit right with me was because it was outside my normal frame of reference, and wasn't so structured. But if I'm trying to break my old routines that may be exactly what I need. Getting outside the comfort zone and such.
The only other solutions that I thought of where to buy a pack of wolves and keep them good and hungry, or jog through south Phoenix screaming anti gang insults.
good cardio if nothing else!
In all seriousness Pardus, I think you hit on something. It does seem to be the closest fit to the "dark parking garage" multi-tweaker realism I'm looking to train for.
