When I consider the number of morons I encounter daily who can’t handle navigation in two dimensions, I get queasy considering their skill with three.
But wouldn't it be fun to zoom over somebody going 5 miles under the limit in the left lane? In lieu of the rocket launcher in the front grill to persuade them to understand the true meaning of "Slower Traffic Keep Right."
If you are off by 10 feet in the X, Y or Z axis in an airplane, 99% of the time you're still cool.
In a car, if you are out of position by 10 feet, 99% of the time you are in DEEP trouble...
Another thing: Who would ever trust a dim with a pilot's license? They are more worried about a bumper sticker than an oil change. Go to any college town and the quality of driving is an inverse ratio to the number of stickers cluttering up the paint. They sneer at redneck mechanical types who know what's under the lid thingie on the front end of the car, but can't change a tire.
Remember that airplanes don’t NORMALLY travel head-on at each other, passing within 10-15 feet (or less) of each other with a closing speed of 120 to 150 mph. :-)
