Continuing to highlight the issue is though a good thing. One day we might just have a rail industry that doesn't overcharge.
I agree the issue of people unknowingly paying
TVMs▸ more than the minimum for their journeys needs to be drawn to attention while it continues to be anything except exceptional. Whether it's "overcharging" or some of those lower fares and wheezes should exist is open to question; I think I would prefer a more uniform system that we (and the TVMs) can understand.
Canvassing opinion here probably doesn't correlate to the wider travelling public.
Most regulars on this forum are probably aware of the limitations of TVMs, and what to do to mitigate against overcharging.
The really interesting question there is "what proportion of our readers are 'regulars'". Looking at our Google Analytics, I estimate that we have between 2 and 3 newly arriving users for each returning regular. And the new arrivals will be different each day, where the regulars are - err - regular.
I appreciate we won't hear the views of the new arrivals here - they read and rarely sign up. We do know that they will ask questions via a chat service, but that's an experiment we switch off because of the enormous resource needed to man it.
The regulars are indeed aware of the dangers of the machines selling a less than best deal - so probably can provide feedback here as to any changes to the machines over the last year. Maybe not correlating wider passenger experience, but nothing does except significant sampling of what people buy, what they needed, whether they got the best deal. And that has to be done by talking to them to see if (example) they bought an off-peak not realising they could have gone for a superoffpeak - or if they bought the off-peak because of their potential return time.
