"I for one will choose to drive without a doubt if the drive is under 10 hours."

Have you done many 10 hour drives? Ever done one in the winter? You can go ahead and say you're going to do that, but somehow I doubt it's reality. Anyone who is willing to drive for 10 hours because security might now take 30 more minutes is driving already. This might sway people's decision if they are on short hops, but not many people want to drive for 10 hours. It's all the discomfort of flying, the hassle of piloting yourself, but with traffic and many, many hours added on.
