What's wrong with bus drivers? Nothing, per se. They almost uniformly receive a lot more training than 'regular' drivers, and their job depends to some extent on how they drive. I am broadly familiar with the training regimen for CTA bus drivers (Chicago) and it is pretty rigorous. The safety record of school buses has been an excellent one, and this has been based in substantial part on how they are driven. This was tragic but seems rather an exception to the norm for school bus drivers.
