Rules 38 and 41. The idea behind it was that the rules complete each other.
However, if there is a general restriction according to which you cannot impede other robots passing, then you are not supposed to 'bump' them so that they give you space to pass.
The robots should not block for more than 6 seconds and that is about it.
Otherwise, if you do not 'signal to pass', the blocking robot would not be considered as such by the judges.

Having written that does not mean I dislike the game.
Actually it is more challenging than that of last year, yet it is easier for rookie teams to be more productive.
