If propane works in the very cold why couldn't natgas ?

Range ? What, you can't fill up a little more often or lose some trunk space.

Power, our vehicles have lots of power, way more than we need.

Diesel/Propane hybrid for trucks has been around for years.

Duel fuel: Sweet I can't wait to see LNG smack gasoline across it's stupid smug face with a pair of gloves.

Silly comments aside I agree with your other poitns and want to point out that using compressed natural gas (mostly methane) as opposed to straight propane would actually be better in cold weather as methane vapourizes at a much lower temp than propane. That's the problem with propane, if it's cold enough, it won't vapourize fast enough to run an engine even at atmospheric pressure.
