That would be cool.. You could have a stage near the screen for political stuff. The snack bar would be online and some honey wearing a mask would come to your car and deliver. You could have a car full of family and friends with no masks on watching the latest movies....
This would rescue several industries... boost employment.. have social discourse with social distancing.. unless you got in a fight with the car next to you (don't ask) You could see new movies for a few dollars a person in the car.. drink beer... If you were a Biden fan you could watch him with the other 3 people that came.
I see no downside to this. Gas is $2 a gallon. cars/trucks hold 6 people easy.. the sound is over your zillion watt stereo.
Like so many of my ideas tho...... sadly.. I am lazy and will not do anything about it. people will do this and make a fortune and I will tell people that it was my idea and they will say..."sure it was pops'
