The plastic gadget: Since each driver has his/her own gadget, there is now a record of who is driving at any time. And since the CERN car has GPS tracking, there is a record of who has driven where. Don't even think about driving it beyond the allowed area. Note that this allowed area is not necessarily the same for everyone – see Mission Order. You can pick up your personal plastic gadget in building 124, as explained in this newsletter.
