Your statistics don't support your claims either, generally they do not provide the following information that would validate whether or not survivability increased.
1. In the real world what was the 1 year survival rate after the accident?
Sure you might walk away from the accident but die days, weeks or even months later from related problems from the accident. Few studies from the "usual" places say much in this regard.
(I can tell you the few studies that go into this area aren't flattering)
2. In the real world what were the implications from collisions at real world speeds aka more than 30mph?
3. When comparing different years are the type of collisions, speeds, etc documented and categorized so trends can be viewed in terms of the type of accident, speed, type of road, and the # of passengers etc. There are many 2 lane country roads I know of that are hotspots for huge numbers of accidents, in fact sections of our local 29 was one at one time until it became a 4 lane road.
When using "general" statistics it is very important what kind of accident it was and what type of road/conditions it was on if you are to compare whether or not the safety of cars or environmental/infastructural changes was to blame for different results now versus when people were primarily driving on 2 way highways. You should also note that cars that have rear passengers many times have one group live and the other not, this is independant of the year of vehicle. So in other words the number of people typically in a vehicle can affect the survivability of an accident.
I can note that during the last 15 years the county has improved how quickly and thoroughly it cleans the snow and ice off the roads including country roads, when I was a kid the roads were rarely plowed except on the main 2 lane highway (there was no 4 lane until recently). And every year they seem to get better and doing it.
Things like this are much more important in regard to the number of accidents and the type of accidents than you may think and in fact I know the newpaper touted a 50% reduction of accidents once the 4 lane went through here. (now to see if I can find it)
There are liars, damn liars, and then there are statistics.
