Mojang has triaged this, so yes, it IS a bug. |

This isn't a bug, minecarts only bounce off solid blocks, and redstone blocks are transparent. |

This bug affects 1.18.1 as well. When a Minecart is moving on a Powered Rail, one of the final checks it does is to see if it will bounce off of a wall. The function it uses for this check will let the Minecart bounce off if the block in question is considered a "solid block." For most blocks, there are two requirements to be a solid block:
However, a block can be explicitly set not to be considered solid even if it otherwise meets the above requirements. Blocks set this way include:
Glass and Beacons already fail the first check of blocking light. I assume that the rest were made non-solid for use in redstone contraptions. There are also a couple of odd blocks out:
Possible fix: Modify the Minecart bounce-off check to work with full cube blocks. Replacing the check outright might make Soul Sand no longer work as it is hardcoded as solid and is not a full cube. |

I would say that because the redstone block is in the shape of a solid block, it should behave like a solid block. It doesn't really make sense how it is IMHO. |

Redstone is a transparent block. Minecarts only bounce off of solid blocks. |
