true that
Whilst exploring I deactivated Sensors and PDistributor. No pips, but not a problem when not fighting.
Actually, you do need both. When you're parking into a station you'll need pips to control your top speed, and also the traditional 4 pips in shields for preventing accidental obliteration by touching walls in particularly high speeds. And also the sensors give you a sense of distance to other ships and even the station itself. Plus, if you're in Open or in a wing, you definitely need it (either for the wing or for escaping crazied CMDRs / griefers shooting people at the station door -- because even though they will be killed, they still have a change of killing you first).
