If they dropped all security altogether, you would still be safer flying than driving. There are a heck of a lot more bad drivers than terrorists.
My objection to flying has nothing to do with safety or security. It has to do with meaningless and ineffective "security" measures that annoy honest people and do zero, zip, nada to stop terrorists.
Not a single measure enacted against travelers will do anything to stop terrorism.
And frankly, I am sick of being treated like a criminal every time I shell out several hundred dollars for a plane ticket. So much so that I won't buy another one until the situation changes (never).
In fact, my willingness to drive says one thing: I desire freedom above illusory safety and comfort.
