I'm losing track of where I've posted! On another mobius thread I said something along the lines - If the only problem with the mobius is that of heat generated in such a tiny space (problems from making everything so tiny then cramming it into the smallest of spaces), why not simply use a remote lens (AFAIK, there is a lens on a short cable (8"?) for the mobius).
Put all the internals into a decent sized box with plenty of vents, maybe add a decent heatsink to one face, maybe add a small fan, keep the battery well away from the main board (or bigger box, bigger capacitor) ...
If we can mount the body well away from the lens then the size and cosmetic appearance of the case isn't an issue.
So it's not like we're asking the manufacturer to come up with anything drastically new & inventive - simply take an existing good product & adapt it for the car market.
If some manufacturers are looking at 360deg coverage, why not put 4 mobius boards into a large case, decent fan, decent capacitor, 4 remote lenses - presto, 360 deg coverage & great cam setup. If the mobius can be linked to smartphone, tablet, laptop etc, software on an app could be used to sync the timestamp of all the cams & even be used to drag files off.
