It affects 1st person as well. You can travel through a 2x1 tunnel just fine, but your head is right up against the top block. This made my nether rail (rail with glass directly above it) vulnerable as a Ghast had line of sight through the top of the glass. Some times you will sink down a little in the cart, but not to the previous level. You have to get into the cart on a slope to get to this level.
I can send more screen caps with debug info pulled up if you'd like.
