Deer are the 2nd most lethal mammal in North America, after Homo sapiens. Striking one with a car is a very well-known way to die.
That is NOT why there are so many accidents.
What's your next theory, people hunting children playing ball is why so many children get struck near playgrounds?
Your are obviously reading impaired, but maybe formal logic might help:
(Finland != America) & (Reindeer != Deer) & (Reindeer == Domesticated_Pig_with_Horns)
