movement inside minecart

When I used to travel in a minecart, I would look ahead all the time I travelled.

Now when I travel in a minecart, every now and the game makes me look around and then I am facing somewhere other than ahead. I wish, whilst in a moving vehicle, to always look ahead.

Get in a moving minecart. Travel for a while. Then it happens. Can't specify how long it takes. But also repeats on turns.

Note that this bug has been in since at least version 1.3.1
