I was inspired by this video to create a better way to enter the nether without having to wait for the nether portal animation.
It's almost instant because it takes 2 ticks to get to the nether (tested using tick freeze and tick step commands).
This design actually allows to get in to the minecart from any angle (in front of the nether portal).
Doesnt work on Bedrock, since it uses qc.
