A visitor from France, for example, where they drive on the right, may not be able to adapt so quickly.
But again, a good driver from France may have less trouble than a bad driver from the UK. It's all relative.
This is why I think that, as well as wearing a V plate, visitors who want to drive here - regardless of how long they are staying, be it a week, month or year - should undertake a compulsory driving lesson.
It would act as a sort of warm-up session, where tourists could acclimatise themselves to the roads and be informed about the laws here, which may differ to those at home.
Overseas drivers are involved in a small percentage of crashes here - a 2015 Ministry of Transport report shows that during the period 2010 to 2014, 5.7 per cent of crashes with fatalities and injuries involved overseas licence holders - but anything that can be done to reduce the number should be.
I'm sure that visitors would understand and some may even be grateful for the driving lesson.
