I understand your point, I honestly do, but as you can see, we\I simply disagree.
You posted a picture that really highlights information overload.... BUT surely you must agree it highlights horrendous potential hazards. Any competant driver would NOT need half of those signs (or indeed any) to actually slow down?
The clearest signs (in my opinion) are the very ones that you say cannot be clearly seen. (warning triangles)
I honestly undersatand what your saying about all the excessive signs, road humps etc and like you I agree they should be culled, but nickmann has already very eloquently and politely pointed out 'our' faults.
When we get behind the wheel of a car WE MUST surely accept responsibility for our actions?
