Late Game Minecarts

Minecarts could have a buff. First, minecarts could now be linked together (up to 8) and the minecart with furnace re-added to Bedrock. next, minecarts could now be enclosed and made so that you take reduced damage while in them at the cost of being slower, essentially armored minecarts, that allow you to make actual use of your rail systems to help you in combat. Fringe ideas/other thoughts: adding the ability to break/stop minecarts with furnace if shot with arrows or if explosions occur nearby. this would also go great with the wood/arrow golem from minecraft legends, which would allow you to move golems with you effectively and actually help you in ranged combat.
