Park & Ride Rules???

I’ve only taken the park ride twice and today I had a very embarrassing moment. So I take the cypress park and ride outbound and it is usually packed by the time I get on so I have to sit in back. Yesterday, I sat at back and no one moved to get off, so I assumed they were waiting on something like a transfer. Today it was the same so I go to get off, and I hear someone say “we’re all getting off”. I got confused but kept walking, then I look up and I see they exit by row. I felt so embarrassed but it was too late to turn around.

So my question is, is there any other unspoken park and ride rules that I don’t know about?

I would like avoid another moment like this.
