Per mile is much better, but also not that good. There are a lot of variables here. How much of driving is at freeway speeds versus how much at lower speeds (where even worse accidents are less likely to cause fatalities)? How good is trauma care in that country (which can turn what would be a fatality in country A into an injury in country B -- and note that part of how "good" trauma care is has to do with how remote from a hospital traffic accidents are)? How modern are vehicles in that country, and what percentage are what kinds of vehicles (air-bag equipped modern cars are much safer than older cars, which are in turn much safer than motorcycles)? What kind of intersection traffic control is there? How good are the roads?
