Hey, it's cool that you ride a bike. I do too sometimes. Other times, I ride the train. Here's the thing: I do one or the other. I don't cram my bike onto the train at rush hour.
If you have your bike, ride it. If you're taking MAX, leave the bike at home. If you do need to shove your bike onto a crowded train, it might be best to say "excuse me", or "can I hang this" instead of just using it as a battering ram while glowering at people.
And if it is standing room only, you have to wait. You can't shoehorn your bike into a shoulder to shoulder crowd. If both hangers are taken, you can't stand there with your bike blocking all circulation. But the best thing would be just to ride the damn thing.
