Back in olden times, when on safari in the jungle, it was recommended that you bring a supply of shiny trinkets to hand out to the natives to avoid becoming their evening meal.
In modern times, the same applies. Bring a bag of EBT cards and a trunk full of expensive sneakers to hand out to the “protestors”, and they will let you pass safely.

Maybe get stickers on all sides of the car that say, “Follow me for your free Obamaphone?”
