Matt Damon won’t care, of course, he’s a major star and he’ll still have enough gelt to buy the limo, fuel it (whatever the price of gas), and have a chauffeur drive him around.
Life becomes a little more problematic for us peons.
Neither does he care that his so called documentary about the evils of fracking is supported financially by the Saudis and will benefit them greatly if he can convince enough suckers to put pressure on to stop fracking from being used.
Like most actors, he wants to make up for his overwhelming fortune gotten by pretending to be someone else, so he picks a "cause" that makes him feel good.
This documentary of his is demonstrably false, much like Michael Moore's agitprop, and it will be used to try to destroy the industry that could, if left alone, bring the US to energy independence.
