Unrealistic turns in boids simulations

Hi, I have a question about boids simulation. Is there a way to improve core algorithm to prevent unrealistic, almost instant turns when new target is behind boid? Maybe some limit to rotation, but how to implement this in seek behavior without ruining other parts of simulation?

I've created simple example with sprite:
