Along with the Element extinguishers this sort of system might be something of high consideration. The USA site is informative:

I like the suppressing agent in that its gaseous and wouldn't leave any sort of residue should it ever be deployed---that's a huge upside over the traditional pressurized extinguishers. My ONLY concern is the triggering temperature which is stated at about 221* F. I don't think there's many places inside vehicles that approach those temps but even so maybe a bit of pre-installation temperature monitoring would be in order, something over a few months? Heat sensitive paints maybe?
I especially like the under hood possibility for my gassers---not sure if the diesel engines running hard would trigger one of these? For electrical bays they'd be great. The switched versions might be interesting for we who love gadgets.
Great find---thanks for sharing!
