FMS/FMCG Discontinuities
S of the Border,
Perhaps misunderstood training is a part of this problem.
In my previous airline, we were encouraged to leave a discontinuity in the FMS/FMCG at the point where you would need a clearance to continue. The green/magenta line on the ND would stop, a pretty good reminder that something has to be done to move on.
Some trainers encourage students to 'connect the dots', or take out any discontinuities without exception to complete their FMS inputs. Personally, I need all the reminders I can get after a long, long day at the office.
