Zombies can't walk over minecart tracks

Zombies/Villager Zombies can't walk over minecart tracks

I was trying to put a zombie villager on a minecart so I could cure him and bring him to a village.

However the villager zombie wouldn't walk over minecart tracks, it would find alternate routes to get to me where there wasn't a track in the way.

Steps to Reproduce:
1. Put some minecart tracks up
2. Try to get a zombie in a minecart
