Mobs stay in place after taking damage. If you put a mob (for example villager) in the car, after taking damage from another mob outside the car, the villager will stay in place and not depend on his seat. Cured by re-entering the world.

"the villager will stay in place and not depend on his seat" I don't understand what you mean by this. Are you saying the villager does not leave his seat?
