I was transporting a lot of items from a place to another, for that I made a long railway and put on 25 Minecart with chest with muy items inside. Then when I turned on my line and I get arrived to my second point with me and all minecarts, i looked that some of them get out of the line (Something that I suposed that it'll pass) but I get nut becous I look to a grass path near to my rails and see that some of my minecarts get into the grass path and continueing  riding like if them were on a powered rail. 

It loocked so funny, then I came to warn over this, I think its cool but it's a bug, I recorded a video of that moment, and I don't know what more things I have to upload here, It's my first time that I report a bug. 

The gameplay and bug was ocurred on Minecraft 1.18.1 without mods.
