Not triggered at all, had you mentioned wheelchair access from the start I might have agreed that it could be better (not that I have any personal experience). I will be sure to observe these things from now on. No need to get snarky friend :)
Not just access, but fast exit as well, also when there is no power.
Not being able to access sucks, but isn't a safety concern strictly speaking. Not being able to get out quickly and potentially blocking the path for a crowd is.
