I know mn pushes that it is feminine to be pig thick regarding.maths, but the lack of understanding of risk is very scary. the road death rate in many countries is much higher than ours, and ours is bad enough.
Again, it's not about maths as you put it forward. Not sure how much you have traveled but surely you can see that in order to work on a straight comparison of numbers you need to be the same in all respects i.e. you need to be comparing apples with apples and apples with oranges. This would include population (number), vehicle factors, road factors and medical factors.
For example, you really can't be surprised about an increased road toll in an Asian country with high population, 95% motorbike use, shit roads, virtually no road rules, entire families riding on one bike, no helmets and no suitable medical assistance at all when they crash.
Have you been to many South American countries and used their roads (and ancient hobbled together cars/trucks/buses with brakes being a bonus)? Again, pretty obvious they are going to have far higher road tolls than places like the UK. If you travel outside the UK it quickly becomes obvious why there is such a difference in road tolls in a lot of countries, and it sure ain't flip flops.
