The alternative (to superluminal) Bohmian view would be trajectories like this (from wiki):

To which Motl adds:
Bohmian trajectories never cross the z=0 plane – the horizontal line in the middle of the picture, in this convention. A particle in the upper half stays in the upper half, and the same holds for the lower half. There's clearly no sense in which this correlation exists in quantum mechanics – or the real world – and this unphysical feature of Bohmian mechanics is also exploited by ESSW to show that the Bohmian paths are "surreal".
