A meteor arriving with several times the Earth's escape velocity is not interacting with the atmosphere that you know; it it interacting with the plasma that is formed by compression in front of it. The streaks left by the sub-milimeter particles of a Leonid meteor shower are plasmas with a measured temperature of 4,000+ deg C; the plasma at the head of the meteor would be much hotter than that.
So it is not cold air that is forced into the crevices of a meteor; it is very hot plasma. The pressure this exerts on the internal structure of the meteor is not countered by similar pressures on the back and sides of the object. Most meteors and bollides will burst apart.
