Perhaps a designated area nearby where cars are expected to park and people and their family could walk to see the show could have been a solution.
If there’s any space nearby that could reasonably hold, say, 50 parked cars. If there’s a mall, or an office building that’s empty at night, within a few blocks you could maybe make it work, but not in the middle of a large area of houses.
My guess is that there would still be problems, though, because it’s cold outside in December and nobody seems to know how to dress for the weather anymore. They’re using the cars as portable heat sources.
