Electric is oil since that is where the electricity comes from that you plug into your home to get.
Natural gas is an interesting option, but of course what happens if a car rolls over in an accident is the big worry.

No, very, very little electricity is produced from oil. Coal, Natural Gas and Nuclear are the primary sources.

Well... you've seen gasoline spill out of a car tank, and your mower refill gas can.

Have you seen LNG/NG 'spilling' out of a pressurized tank? Even if you roll it down a long hill?

Doesn't gasoline have a higher energy density than LNG/NG ?

Is a car gasoline tank more susceptible to explosion when it is full, or when almost empty?

Back in the 60's and 70's many farmers in West Texas converted their pickups to run on propane. The propane tank was bolted to the bed right behind the cab. Power was about the same, but mileage was worse with propane that with gasoline. Also, because the engines were designed to run on gasoline, you had to run some gasoline just to keep the seals from going bad.

There were a lot of wrecks, but I do not recall any where the open exposed propane tank exploded.
