I think it has more to do with culture than number of vehicles, the countries with high deaths are all in West-Europe. I would be able to predict that without even looking at the graphs, in Italy, Spain,.. they drive like a madman in big cities. For most of the other countries, the differences are really minor which imo are random or can be explained by traffic regulations or differences between the countries. I think it's the same with programming, the size of your program doesn't matter but the culture does. If don't use any system to develop, test,.. and don't really care about good code you will have bugs. On the other hand, with a good system you will have less bugs. If the argument of the blog post was true, then you would have more bugs if you use more libraries? Or the bigger the libraries you use the more bugs? Doesn't make any sense.
