Mine carts will get stuck over powered rails if they are activated with the mine cart on top of them. This will occur while the player is both in and out of the minecart.

In all examples. the rails are activated by either switch or timer, after the mine cart is placed on top,
Well, in which direction should the Minecart move?
Powered rails can only start pushing Minecarts into a direction if it's clear into which direction they should push it. So there either needs to be a block on one side of the rail, or the minecart already needs to be moving into a certain direction.
