Genuine question - is David's Rd actually one-way, as a couple of people have said? It's no entry from the S Circ of course, and there have been plenty of times I've waved at cars going the wrong way (I thought) up the street. But I have just realised that there are no one-way signs down that end, and the sign at the junction of Pearcefield (which is sign posted as one-way) warns that you are going into two-way traffic.
The ambulances often turn right out of their car park, and I'd always assumed that they were using special emergency vehicle privileges but i think I was wrong...
