RE: Safest way to play while waitingThe problem with cars on NG is the infrastructure required to make NG readily available... too costly... not likely...
They can run heavy duty trucking on NG but infrastructure and ability to carry enough LNG to get any distance isn't practical. See Westport Innovations and ask yourself why they haven't tapped the market outside of fleet vehicles with local haul only and yard equipment at ports... that's the reason.
