Is driving an armored car/truck dangerous?

I see a lot of armored cars/trucks and their drivers delivering money to banks on the streets near work. The cars are heavily armored, the drivers wear heavy body armor, carry sidearms, and are usually pretty fit, and I assume they are well trained. But the only armored car robberies I’ve ever heard of are on the old Superman TV show or CSI: Miami. Does the armor and weaponry on prominent display actually render a robbery so unlikely that driving an armored car is a safer job than say, bank teller, convenience store clerk, or police officer?
