"Street Outlaws" star Daddy Dave was thumbs up during his hospital stay ... even though he can't remember why he ended up there.
Dave's wife Cassi tells us Dave is healing up pretty well after the accident ... and was released from the hospital early Monday. He'll go back home to Oklahoma to recover.
We're told he's been having problems with his short-term memory after suffering a concussion from the horrific crash. He's been told numerous times what happened, but he keeps forgetting.
As we reported, the accident occurred Saturday.
Dave's lucky ... and his family keeps reminding him of that.
