Why so many gloom and doomers on this site

It’s like people buy these old cars thinking they’ll be able to go to “Advanced O’Reilly Zone” and get whatever they need for a few bucks, and then it’ll bolt on and fit like a factory part.
As for the gas, its stupid to think ALL gas cars are going to be gone in 5 years when probably 99% of the population rely on them. Gas prices always change, get over it.
