How many would there need to be to get your attention?
Being killed by lightning is about 1 million to one, being killed in a car crash is about 20000 to one.
So if you spend time thinking about which seat you're going to sit in when you fly to minimize your risk of dying, you are completely wasting your time.
When you bring "chances of survival in a plane crash" into this equation without considering just how astronomically low your odds of an accident are, it's time wasted. IMHO in any reasonable, objective selection mental heuristic the size of this factor is so tiny as to be easily discounted.
