I retyped my response a couple times, because I mean to ask a non-inflammatory question (I do think the V1 is a great unit). Don't you slow down, regardless of whether the cop is behind or in front? At best, I've always viewed the arrows as a nice-to-have; they'll let you know which direction to look out for lights (unless, perhaps it's cop running radar, calling ahead to other patrol vehicles waiting ahead).
