Options for getting down the mountain after parking

Newbie here, I will need to get down mountain every day to run at lower elevation. Everything I read says you can’t move your car once it is parked. Staying at Mary Ellum - no parking pass. Are there any options for getting down? Why can’t cars be moved?

You should be able to park your car near Mary E. and not have to go up to Mountain Village to park. You are not prevented from moving your car once parked, but if you do you’ll likely lose your spot and have to park further away.

no reason to drive, and no where else you can park, shuttles running every 15 minutes.
