What kind of pilot? There's a world of difference between someone who's tooling around in a single engine Cessna on weekends and a guy who is pushing a fighter jet to its limits in order to stay alive. There's a world of difference between someone who does it every now and then for fun and someone who does it to pay his bills.
I think that anyone can become a pilot. It takes different people different amounts of time, but pretty much everyone has the physical coordination to learn to fly. Most people capable of functioning independently have the mental capacity to learn the regs and so on.
But to do it for a living? That's a different kind of flying altogether.
A lot of horrible drivers wouldn't be horrible drivers if they set their mind to it...
You know, like hang up the cell phone, turn down the stereo, remove the giant piece of vinal from the windshield of their rice rocket, un-tint the windows so they can see something, sit up straight, tell the kids to shut up, eat meals at home not the car, and finally...allocate just a small amount of brainpower to "stay ahead of the automobile."
I don't like to equate flying with driving. They have some similarities maybe but that's it!
The qualities a professional pilot must have to be safe.
1) Situational Awareness. "Where am I?"
2) Foresight. "Where am I going to be in 5 minutes?"
3) Memory Recall. "What are the emergency procedures?"
4) Decision Making. "What do I do RIGHT NOW?"
5) Flexibility. "How do I get along with this guy for a month?"
If something breaks in a car you can pull over. Nah they are not the same at all
