LHD driver driving in another country with RHD vehicles?

I usually drive a RHD vehicle (since I live in the UK) but I have driven a LHD vehicle in the US. I didn't find it a problem at all to switch from RHD to LHD. The foot controls are identical (right foot - gas and brake, left foot - clutch, if applicable). The only real difference is the position of the stick shift and the handbrake, which work identically but are on the other hand. The hardest thing to learn is the priority system, which may not only be mirrored but may be different to the priority system in your country. In the UK, for example, traffic on a main street always has priority over traffic entering from a side street. I believe that some countries, at least in towns, give priority to traffic entering a main road from the right. The US also has different rules of procedure at an intersection. In the UK we have many roundabouts (circulatories?). I believe that they are a novelty in the US. I have also driven a RHD car in France and found it less of a problem than I anticipated. The only awkwardness is that one needs to adjust the wing and rear-view mirrors and, usually, the offside mirror is not ideal for checking traffic before pulling out to overtake and, of course, it is harder to 'see round' the vehicle in front. One just needs to exercise a little more care and attention at all times.
