Welles and the automobile

[Colmena]

Given the negative role of the automobile regarding the parallel decline of the Ambersons and their city,
did Welles ever explain, in interview perhaps?, why he didn't drive, and so needed to be chauffeured?

Did he drive when young?
Or never?

I'm guessing that Welles was much more likely to be driven, than to take the streetcar, in the leisurely & idealized manner of Ambersons' opening scene!

[Le Chiffre]

Welles told Barbra Leaming that he drove an actress home one night in the forties. She accused him of rape, and to avoid publicity (he was married to Rita Hayworth at the time), he paid the actress off, and never drove a car again.
