ETA: I think that analogy works rather well, now that I think of it. Consider why sports cars are more expensive to insure. Is it because they, as automobiles themselves, are more dangerous, or is it because the types of people who purchase them are more likely to speed and wreck?
There are multiple factors. Vehicle cost, location, driver age group, accident history. I'd imagine collision on a late model Rolls with a professional driver would be much greater than a '70s MGB driven by an accident prone driver.
As far as "vizlas" go, all three that I had experience with were put down because of violent behavior. Your mileage may vary.
When I kicked my FIL's dobermans that went after my son, they were all over the dogs saying, "There there babies. It's OK." I asked them if they were crazy. Didn't they realize their dogs had attacked their grandson? I'm not saying you're the clueless dog owner type who think their 70 lb dog is not capable of hurting anyone, but certain dog breeds have a greater risk.
I don't care if you get a pit bull and feed it gunpowder. As the dog owner, YOU take the responsibility for what it does.
ETA: Sorry. One of my pet peeves are dog owners who don't control their animals and inflict them on their neighbors.
