Desparado,

The untrained driver should have stayed in the bus, and I'd think it is likely he will at least get a tongue lashing. On the other hand, if he thought he was doing good, was trying to do and in reality did little harm, I would not want it to go that far.

However, your family should get a round of applause. I find too few people today are of the mindset to stop and help when they see someone in trouble.
