Now mind you these are just people I know nothing about who are saying this, so I am not putting this forward as anything other than idle rumors at the moment. But given how many things scientists have had to back down on with revelation of better information, how interesting would it be if this 'new information' is correct and petroleum is a renewable resource? And how would this affect global policy?
I believe the hypothesis is that methane was present in large quantities when the solar system formed, so we have a near unlimited supply of natural gas. But I don't think it applies to heavier hydrocarbons.
The biggest impact potentially will be on the climate. If we run out of hydrocarbons to burn, and burning hydrocarbons causes global warming (as seems likely to be the case), then "running out of fuel" could save our environment.
On the other hand, "an unlimited supply of natural gas" isn't nearly as bad for global warming as it would be if we had "an unlimited supply of coal".

The Hindenburg didn't burn because it used hydrogen. It had serious safety problems.
Of course, any time you have a vehicle engulfed in fire, any fuel on that vehicle is likely to contribute to the fire.
