I found when using powered rails I have a lot of glitching. Sometimes the display shows me flying off the track and into a group of blocks rendering me without vision and later returning me back into the mine cart further along. Also I find there is a significant increase in strength, where before i used 3 powered rails together between every 16 or so blocks, now I need one every 50 at most. If I use more than one per fifty I get another glitch with the mine cart as it speeds away at a constant speed for a random duration until it comes to an utter halt with no way of knowing when it will do so.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Is this occurs in multiplayer only? Looks like client-side prediction when latency is high. The same causes squids fly in air. Client extrapolates position of moving entities by treating that it moves with constant (vector) speed as it knows last time.
However, prediction can be improved to follow rails, instead of just extrapolating linearly, for entities that bound to rails (like player riding in minecart).
