Liquid gasoline is stable and not explosive.You need to better research. You should definitely fear and take precautions around gas ... IT IS DANGEROUS.
Yes the liquid burns, and the vapor burns even faster, so fast fact that it is explosive. How do you think that it works in your car?
Why you would say this is beyond my fathoming. I really hope that you don't store gas with this attitude you are going to hurt someone or destroy a lot of property.
Look up what happens when you store gas in containers that are air tight. You need special containers for this, especially in a non temp controlled environment.
Vaporized gas has lots of oxygen around and can easily ignite from a spark.
As long as it is stored properly it’s very safe in liquid state.
An engine is different from your gas tank. There’s also a reason cars rarely blow up.
Responsible handling is good, but fear is bad.
