You forget that most people don't live or work next to the rail station. That makes rail inefficient in the only way that matters to most people - their time.
(I say that as someone who takes trains to work most days.)
I think trains going twice as fast as cars and not being impacted by traffic goes a long way in making up for the last mile problem - even if you take a bike for that piece, overall you're gonna be much faster than if you're stuck in rush hour traffic.
Plus, in the context of the looming climate catastrophe and the energy crisis caused by a war of aggression by our former primary energy supplier, that concern seems really petty anyways.
