years ago, when I was baout 18, I visited some family friends in France. My hostess met me at the station to drive me to her home, and spent the entire journey telling me all about the history and architecture of the area we were driving throuh. Which was lovely, except that she kept gesticulating, and half-turning to face me. Which meant that a lot of the time she had only one hand on the wheel and wasn't looking at the road.
I don't think I've been so scared in a car before or since. (except maybe once with a taxi driver in Florence who reversed a top speed down a very narrow one-way road..)
