I think that anyone who drives around/over water on a regular basis should think very seriously about stowing a pony (escape) bottle and a mask under the seat.



Storing compressed air tanks in vehicles is very problematic. First heat build up in cars can lead to o-ring failures. And in freezing weather regulators can ice over, most likly just causing free flow. I could really list a whole host of problems but I take 2 ferries to get to work every day and have about a dozen or so scuba cylinders and I wouldn't even consider storing a tank under my seat for very unlikey "what if scernario".
