[MC-32] Minecart going in a circle will make any minecart close to them go super fast.

This bug has bin in the game for a long time. The problem is that when you place rails in a circle (2x2) and place 3-4 minecarts, and spinn them in the direction you want, the minecart on the railine next to the cirkle will go super fast, an the momentum is forever.

Thei are not boosters, it is a bug, because the minecart goes forever.

I can confirm this in creative mode.

Sometimes the carts in the circle will follow me when I go past it.
Sometimes after I reach the end of the track I will move across grass for about 20 blocks before finally stopping.
If I have a circle on both ends of the track, when hitting the second circle of carts, I will immediately be sent the opposite direction.

SethBling showed off this trick a long long time ago. It is an old bug that was never fixed.

It was fixed and then re-introduced later on for some unknown reason.

Is this still a concern on Minecraft 1.4.4 Pre-Release? If so, please update the version affected.

I thing this bug is awesome. You can send a minecart to max height with no powered rails BUT if the stacked carts fly off their circle they will travel forever in a direction even on no rails. That is kind of buggy and causes problems.

Can you replicate this issue in latest version of the minecraft? If so, can you please update the ticket?

I can confirm that this is present in 13w09b. It seems to have to do with multiple collisions between the individual entities all adding momentum to each other and transferring that momentum to passing carts.

On a side note, while attempting to test this I encountered a couple of other bugs:

1: If you enter one of the carts that is on the circle track and then get off, you can end up being placed 1 block lower than the level of the track.

2: (possibly related to #1) Entering one of the carts while trying to set up this glitch can cause a crash. (log attached)

PS: It appears the momentum gained is not infinite, as the cart will eventually slow down again, unless one of the glitch carts follows you. Tested by placing a long line of inactive powered rails after the launch rail; average distance when not being pushed was about 40-50 blocks before the cart stopped, being pushed will keep you going well past any powered rails you may have set up.

Crash while attempting to test the glitch. Based on the crash log, it looks like I somehow ended up riding a minecart that was riding a minecart...
