I don't mean I drive in a fast way like racing around. Just round my way there can be quite a few country roads and lanes and I just drive whatever I feel is appropriate.
The speed signs I see as targets are the maximum speeds for bends on some motorway junctions - I always see how much faster than their recommendation I can do easily.
I'm not sticking a 'Like' on your post because it implies I agree they are targets.
But .....
These are usually warnings rather than limits. And the problem I have with them is that they are so conservative that people tend to ignore them. Which means that one of these signs place on the entry to bend where it is a 'real' warning then it is too likely to be ignored.
