Honey block minecart and slime block minecart

The honey block minecart and slime block minecart would be 2 new variants of minecarts each with similar but different minecart, item and block interactions. Minecart linking: When either a slime block minecart or honey block minecart collide with another minecart, of any type*, on a rail track it will link to that neighbouring minecart. A single slime block minecart or honey block minecart can only join to the neighbouring 2 minecarts infront and behind it, however a honey block minecart or slime block minecart can be joined to a minecart that is allready attached to another minecart, within a limit. *Honey block minecarts and slime block minecarts can not connect to eachother. Sliding and bouncing: When a honey block minecart collides with a wall it will stick to the wall and slowly slide down it if the minecart is off of a rail track, it will also slide to a stop if rolling on blocks, and will ignore the wall bouncing effect of a powered rail leading into a block. Slime block minecarts however will bounce whenever they hit a block, and they will always have the bouncing effect of a powered rail leading into a block. Item interactions: If an item is thrown onto the top of a honey block minecart the item will stick to the minecart, whilst on the minecart the item can be picked up by players or mobs such as the allay. If the honey block minecart is on a powered activator rail it will lock the item from being picked up. Items bounce off of slime block minecarts.
