When the car's automatic gearbox breaks down, it is nice that there are some mechanics around.

True, but not everyone with a license needs to know how to rebuild a gearbox =)

Depends, on some countries getting a license means acquiring basic repair and first-help skills. :)

In any case, the point was that those that know how to repair the gearbox must come from somewhere.
