I have a auto FWD 93 L.
When most auto cars are in gear and driving and the ignition is turned of you have to put it into park before you can start it again.

Well i was wondering if it is normal for me to be driving my car and turn the ignition off and be able to turn the car right back on. But it never fired up or anything it just was on again.

Is this ok for my car?

It probably hasn't died all the way yet and there is still enough RPM's to get it going again.
