I know it’s fun to pile on, but I can see the OP’s point.
I agree. In the old days they used to have very clear “no entry” signs – big read things with a white bar across the middle, you couldn’t miss them. Sometimes they had “except buses” or taxis, or bicycles, or whatever, written on them.
Now they have these pale blue signs with loads of small pictures on them that you have to decipher as you’re driving along unfamiliar roads.
Central Croydon is a nightmare with regards to this, they have pale blue signs with pictures of trams, buses, bicycles, and the word “taxi” on them, in various combinations. And just to properly confuse you some of the pale blue signs with pictures of trams on them only apply certain times. So you have to work out what the picture on the sign says and what time/day it is, whilst driving with someone up your arse and trying to figure out what turning to take.
It’s bad enough for local people but for someone who doesn’t know the area it must be a total nightmare. Bring back the red no entry signs!
