I love how people just come up with this shit with their knowledge of their local area. Any train here requires driving to, and does not come and go frequently, and takes longer. Our infra is terrible.
On the flip side, some places have awesome infra and I wish I had that. I'd prefer to pedal bike if I could. But where I'm at you're very likely to be killed without bike lanes or sidewalks, and it would take hours to get anywhere important - IE work.
