Motorists of North Wales: when I am approaching a roundabout at the bottom of a fairly steep hill my attention is on many things: blinking through the pissing howling wind & rain, braking, looking to the exit on my right (which is largely obscured until about 10 m from the entrance to the roundabout), attempting to discourage the motorist behind me from overtaking (or indeed undertaking) me on this single lane entrance, staring out the motorists to my left who really, really want to pull out in front of me, and the cunningly placed manhole covers. I do not need the extra task of avoiding your spilled diesel or petrol. Learn to fill your vehicle properly, return the cap, and for fuck's sake get the leaks fixed. Is it really too much to ask?
