Despite raising the minecartMaxSpeed using the gamerules, the minecart's downward velocity remains capped. This can be seen when trying to ride a fast minecart downwards or when observing a derailed minecart fall (it falls much slower than other entities).
Steps to reproduce:
Build a vertically diagonal track with powered rails
Set gamerule
minecartMaxSpeedto 1000Enter the minecart
Compare the behaviour of the minecart going upwards and downwards
Observed result:
The minecart hits a speed barrier several times when going downwards:
In my testing at maxSpeed 1000 going upwards from bedrock to world height takes 9 seconds but going downwards takes 20 seconds due constantly hitting the speed barrier.
At even higher speeds (you first need to accelerate on a looped track) the minecart will instantly derail because it's moving horizontally much faster than it's allowed to move downwards
Expected result:
The minecart would respect the new speed limit when traveling downwards.

If there's a speed barrier, it seems to be 19. If you have a rail going downwards about a 100 blocks tall without using any powered rails, it only bumps if you set max speed to 19, but not when its 18.
No that's incorrect. The speed barrier is 16 bps which is what the minecarts terminal freefall velocity is. (that's hilariously low ngl)
You can notice that on powered rails (it starts to hit bumps at maxSpeed 17).
The reason it's a bit higher on regular rails is they provide no acceleration so the drag is more intense.
