Rush.. the proper way to compare air travel safety and auto safety is not by looking at deaths per mile. A real comparison is deaths per trip. If you get on the conveyance will you get off alive?
A cursory look says about 15,000 passenger flights per day. Let’s call that 50,000 to be generous. That’s a lot of flights. That’s also a drop in the bucket compared to the number of car trips.
Cars safe. Air travel much less safe. Get in a car and the odds of exiting the car alive are high. Get on a plane and the odds of exiting the plane alive are not as high.
