Yes, but only on the bus. The reason is because sometimes I didn't see the bus stop sign in time to press the stop request ribbon. But I usually get out at the next stop and walk back to it in that case.
I've never had it happen on the train because the train stops at every stop, so I know exactly when I'm at a point where I can get off.
I think what helps is that I'm not the kind of person that can relax in public well enough to even look at my smartphone for more than 20 seconds, let alone fall asleep. I'm too anxious with all these other people around and the fact that I'm inside something that's moving to do anything other than stare out the window and glance around observing everyone nervously. Also, I'm trying to act like I have good social skills... so that means I don't want to be focused on a device that will make me irritable if I get distracted. I don't like the way I tend to either snap at people or act incredibly dazed/confused if they distract me while I'm on the computer or something, and it would be humiliating to have that happen in public.
I mean, seriously, one time someone tried to ask me a question while I was focused on a device, and I looked up, and said something so incoherent they thought I was on drugs. I think they asked me what classes I was taking, and I responded like this...
"Oh, I'm taking the classes that are listed on that thing."
"On what thing?"
"That thin, white thing... you know, like the stuff you print documents on?"
"Paper? But don't you know where they are?"
"Yeah. They're in the hall in one of those buildings."
"What are they like?"
"There's the hard one with all the numbers, there's the one where I'm on the computer, and there's the one where I read and do quizzes a lot."
"Who are your teachers?"
"An old guy, an Asian guy, and an old lady."
"Wow... umm, good luck, dude."
So this is why you're unlikely to see me focusing too hard on something like a smartphone or a laptop in public. Because if someone tries to talk to me while I'm in that focused state, they'll get answers like these at best. Some part of my brain views these answers as basically equivalent to the correct answers to the point that I don't realize that there's anything wrong with what I'm saying until someone points it out, and then I can get really irritable and defensive about it once I "come to."
