An "inconvenient" trolley that only the player can ride.

Trolleys can be used for a variety of purposes, but because of this, they are also prone to accidents.
(Mobs can get on it and disappear on their own, or they can go far away with just a little push.)
Many players have spent a lot of time dealing with this.

The attacker escaped with the trolley, and the raid on my village didn't end until I found him.

-Only the player can board.
-It will not move unless a player is on it.
With such a special trolley, various problems do not arise.
It probably exists "just for simple movement". However, that is the most common use for a trolley.

A regular trolley that is dexterous and versatile is of course useful and essential.
Apart from that, please give us a new trolley "for stable transportation".
