I tried it once many years ago and BF at the time had to grab the wheel as I veered over to the left after turning out of a junction. I found it better on roads with a central reservation, but a nightmare 'around town'.
DH claims it's no big deal and has done it before, but I feel it unfair to let him do all the driving. Is it something that comes with practice? (Trouble is, where can you practice, one mistake could be fatal...)
Also, how easy are the road signs to understand? I speak basic French and German but cannot guarantee I would be fluent in road-speak. DH speaks neither and seems remarkably blase about the whole thing.
