Hello, I am an avid Minecraft player from Pennsylvania. I request that Mojang revamp rails and minecarts as follows.
1: Minecarts can have unlimited speed
2: Add vertical rails and make it possible to create loops 
3: Powered rails should have 3 speeds. Current speed, 2x speed, and 5x speed.
This help would everyone who builds roller coaster in MC for fun or as a way to get around area in their Minecraft world.
These propositions would have came in handy when I built a MC recreation of Millennium Force from Cedar Point, and would help everyone who like making coasters and or people who want a faster way to travel.
These changes MUST be done to both Java and Bedrock.
