    Description

      The bug

      Chicken and spider jockeys riding a Minecart can control it. This should not happen as you are normally unable to move with Minecarts when you are not on rails.

      This seems to happen for mobs which AI is overridden by default, so chickens and spiders:

      Chicken Jockey
      /summon minecraft:minecart ~ ~ ~ {Passengers:[{id:"chicken",Passengers:[{id:"zombie"}]}]}
      
      Spider Jockey
      /summon minecraft:minecart ~ ~ ~ {Passengers:[{id:"spider",Passengers:[{id:"skeleton"}]}]}
      
      Skeleton Trap
      /summon minecraft:minecart ~ ~1 ~ {Passengers:[{id:"skeleton_horse",Tame:1b,Passengers:[{id:"skeleton"}]}]}
      

      Note: For spiders and horses the movement seems to be inversed so they move away from their target
