This is true. The driver ought to be able to get within 30* of the goals - if there is an onboard camera, then within 15* without much difficulty; having a turret with 60* of turn ought to be more than sufficient.
Having lots of slack wire to compensate for a turning mechanism can be dangerous. In the past when we've had telescoping parts we've used coil tubing found on air compressors. The coil would stretch when extended then return to a coil when retracted.
(I almost used the example of a telephone cord, then I realized there may be quite a few people here who don't know what that is/was.)
