Driving in countries where they drive on the other side of the road... [View all]

Yes, USA. I'm talking about you specifically, but also Europe. My brother's going to the US in November and he's going to pick up a car in LA and drive all over the place, including in large cities. I think this is a bit of a worry, because I've heard of things like this one where not being used to driving on a different side of the road causes a huge prang.

My brother insists he's a really good driver and I'm underestimating his awesome driving skills, but I know from switching from a European car to an Australian built one how easy it is to slip into normal habits without thinking. The steering column of my old car had the wipers and indicators on different sides than my new one, and after six months with the new one, I'm still finding there's times when I go to indicate, only to find I've turned my windscreen wipers on.

Any advice from anyone who has successfully mastered driving in built up areas on the other side of the road than what they're used to at home?
