Did they have drivers' ed. classes at the asylum?

I wonder if he had access to television while at the hospital as well.

this is a major plot issue.

If Michael Myers had some sort of supernatural power that would have him survive after being stabbed in the neck, stabbed in the eye, and shot multiple times in the chest, then surely he could've tapped into it for the simpler task of driving an automatic transmission station wagon. Regardless, he could've observed the basics of driving from any 70s television series.

"WYNN:
Sam, Haddonfield is a hundred and fifty miles from here. How could he get there, he can't drive?

LOOMIS:
He was doing all right last night. Maybe somebody around here gave him lessons."

Bribable employees are nothing new.

You just do not know these things. Dr. Terence Wynn is a minor character in Halloween. He tells Dr. Loomis that Michael Myers could not have gotten far because he cannot drive. Loomis says that maybe someone at Smith's Grove gave him lessons. However, it was Wynn, head of Smith's Grove sanitarium in Halloween 6 who taught him how to drive.
