I'd love to own a gas guzzler, a good V8 sounds better then some horrible neat refined hybrid type utility vehicle. Its not that terrible a choice as you can always convert petrol to LPG and more then anything else USA has a ton of propane gas from fracking, enough for 50 years of supply apparently. The main difficulty being transportation is harder then oil as its a less compact energy source. Coal is actually the most calorific energy type to transport believe it or not.
Anyway the V8 fuel thirsty vehicle will run off LPG, the fumes it outputs are mostly steam not the deadly type that petrol needs a CAT to neutralise. Its really wrong that we dont just go that direction already so maybe a black swan event would be a positive eventually, I dont believe in subsidies etc for this reason. Face is there is oversupply in alot fuel and its not oil in USA, there is still not a net export
You simply can't just take and plug an oil well and unplug it later, see what happened in the Gulf of Mexico in 2010
Excessive methane content caused that and if they had respected that variation in the supply it would be controlled. After it blows up and so deep of course it was a disaster to stop
