It's a lot more than a "small minority" of people that wouldn't want no access to a bathroom for 3 hours (we need to include the drive time, remember). But yes, you could do it safely if you required people to stay in their cars the entire time and provided no services, not even bathrooms. I honestly don't see this being that attractive a proposition to most people though. And I've never been to a drive-in theater in my life, so I don't know about restoring normalcy. Restoring normalcy would be going to a regular theater. A drive-in theater would be a novelty that I'm only experiencing because of the pandemic.
