Left hand driving attribute?
I apologize if I missed this, but I cannot find anything in the 1.4 spec that indicates that a particular Road is for left hand driving (driving on the left side of the road) or right hand. Is this in the spec somewhere?

I don't think there's anything at the moment. However, there is some discussion on adding a country code in 1.5 (see #6441). From this it would be possible to deduce left- vs right-handedness.
Hmm. That means every simulator has to have a list of left-hand drive countries? Wouldn't it be simpler to just add left-hand to a road (or at least, to the header) as an attribute? Also, looking at representing larger road networks, how would you represent a network that crossed country boundaries?

We could extend the "<road><type .../></road>" entry with an attribute in order to cover this requirement. If nothing is given, then the right side driving is assumed otherwise each road needs to be attributed e.g. with
<road name=...> <type s="0.0" type="motorway" leftSide="true"/> </road>
or we make it easier and just make it an attribute of the road header
<road name="myRoad" ... leftSide="true"> : </road>
