"Newer cars are much better than older cars". How about this?

It'd be weird to ask for evidence of that statement cause it's very generic and there's like a million instances of newer cars that are shit and old cars that are brilliant. But in general the statement totally holds and you'd need to be insane to be arguing otherwise.

Having 27 years of driving cars experience would add weight to the opinion stated, but otherwise not provide any substantive credible evidence.

I only have 17 years of experience and I fully agree with the author here. This is my personal opinion and I would not be fucked to respond to any demands for evidence since those demands are not meant to be satisfiable in the first place.
