Irresponsible portrayal of destruction

I want to highlight how destruction was handled in the climatic car chase scene. Cars are flipping and blowing up and smashing into other cars and buildings. The big safe is ripping through everything it touches and is sliding out of control. And yet the only fatalities are those of the corrupt cops chasing Brian and Dom. Now, I know why this is so. How can we like our protagonists if they kill innocent bystanders? It makes for unlikable heroes. But I think that is letting them off way too easily. In none of their planning do they make any mention of whether they are endangering the citizens of Rio. In reality, there would have been a lot of people killed, and I think it is wrong to not show any pedestrians dying in the destruction. It's expected that in movies reality is bent a litte, particularly in big-scale entertainment movies like this. I get that. But I think it was done to an irresponsible degree in this case.
