Just for the start: • there are some "no left turn" restrictions in Munich that only apply during rush hour (i.e. specified intervals on a sign) to improve traffic flow, with day_on… not being sufficient • there are some "no u-turn" restrictions in Augsburg that only apply to vehicles longer than 6 metres • there has been a "no right turn" restriction near Neusäß that only applied during night time and holidays (got removed a few years ago) to calm down a residential road None of these are representable implicitly or with what we have right now, and those are just a few random examples off the top of my head; I have seen a lot more of them.
