I finally did it! The look of panic on the man’s face is an expression that I won’t be forgetting for a while. I know it will have been reflected in mine as the realization hit that I was, indeed, driving on the wrong side of the road.
I guess it was going to happen at some stage and, as we have been in Switzerland for three months now, it’s fairly impressive it hasn’t already occurred. Thankfully I noticed in time and did get back to the correct side of the road before the other car hit us, narrowly avoiding a head on collision.
