Let's talk about Em's Minecarts! (carts)

Lastly, minecarts

I think the biggest issue with minecarts at the moment is that they feel unfinished)

I'm gonna start off with something that has just fallen under my radar due to my testing: https://bugs.mojang.com/browse/MC/issues/MC-71998

This bug is really annoying for trying to make minecart tracks which have automatic track switching. At the moment, there's only one reliable way to be able to pass items from the player to a way to detect which route to take and that is a minecart with a chest boat inside it. The only other option is having the player travel right in front of or behind a minecart with a chest, but this doesn't work very well in practice without adjusting things specifically to accommodate that. My proposed solution is to either make a minecart with a chest that a player can also ride in, or make attaching minecarts together much more intuitive and straightforward (a popular request being able to chain them together)

There are also minecarts (just 1 really) that feel kind of useless and that's the furnace minecart. I think the fact that it travels so much slower than regular minecarts really take away from the potential to have long trains being fronted by the furnace minecart with passengers and cargo. I think it should just only be able to travel at 1 speed (maybe like 16m/s) and need to be fueled.

I'm sure there's many other things to do but I will leave it as such. Thank you for reading
