Honestly it took me longer than I would like to understand what I was looking at, that said once it made sense it's a neat idea. I know from experience though that your target audience is people who already understand it, getting this 'standard' will be very challenging to have mass public transport users adopt.
I do have some concerns too about the failure rate, although I haven't quite figured out how you're actually calculating that, still going through it. But seems worrying, do you have some plans to address it in the future ?
I don't have plans. I'm not in a position as of now to even know what to do next.
I meant it as a proof of concept. If an industrial player would like to experiment with an easy to use variation, i would be thrilled, but i don't have the tools.
