Thats some really impressive stats.

I think this is a combination of great safety equipment, the safeness of the car itself (crash tests and so on) and the people who buys it. Its not the most hardcore drivers who buys a Volvo, even tho the 2017 and newer models are really good looking. Volvo has always been a pioneer in security as well

Define "hardcore driver". Is it someone who drives aggressively and takes dangerous risks?

Yep

TheNewBoston's youtube channel also has some nice math videos that might help someone. Not sure if its applicable here. https://www.youtube.com/watch?v=UxhMTi2bh7k&list=PLAF739DF5F...
