I have the activation of "Do Not Disturb While Driving" set to "Manually", because I don't drive very often and therefore have no use for this feature. Every time I'm on the subway though, I constantly get a full-screen pop-up asking me to set up "Do Not Disturb While Driving". This pop-up gives you only two options: To either turn on the feature, or to set it up later. However, it provides no "Don't bother me with this ever again" option, so every time I'm on a subway train, iOS is bothering me again and again to activate DND. This **** is annoying the hell out of me. Am I the only one? Why hasn't there been a huge outcry yet? Everybody using trains, subway, or even the passenger seat must have the same problem.
