Kent County Council must have calculated that its plans for a £350 cap limiting the use of the Freedom Pass would trigger some controversy.
But any hope that it could ride it out and persuade parents and children that the new arrangements still represented a good deal is failing on quite a spectacular level.
Mounting pressure over Freedom Pass changes>>>
If you wanted an illustration of the backlash, you don't have to look very far. Two petitions calling for a re-think have already attracted about 8,000 signatures. One has been started by a Conservative councillor in Shepway, which must be pretty galling for County Hall.
Even schools are encouraging parents to get on the case, sending out messages on social media linking to the petitions.
There are mutterings in the corridors of County Hall that some backbenchers are not terribly impressed and speculation that come the budget meeting, the opposition parties will join forces and try to block the changes.
KCC's dilemma is that the scheme has proved too successful and as a result, is proving a drain on its dwindling resources. Not many councils could sustain a discretionary service costing £13m a year to run given the relentless pressure on their budgets.
It is doubtful, however, that hard-pressed parents who fear they will have to fork out hundreds of pounds once the £350 cap is reached will have much time for the distinction between mandatory and non-mandatory services.
Containing school transport costs is undeniably a big issue for Kent, partly because it is such a large county.
One of the key principles behind the Freedom Pass was that it was designed to enhance the concept of parental choice when schooling was concerned. It is impossible to know, but there will be many parents and children who factored in the availability of the Freedom Pass when making choices about schools.
The scheme was also lauded for its impact on cutting congestion during the school run and environmental pollution around towns but we are not hearing much about that, despite it being an integral part of KCC's "Growth Without Gridlock" agenda.
It is only two years since the county council made an equally unpopular decision to end a scheme that gave help with transport costs to those attending grammar schools and church schools, depending on how far away they lived from the school.
At the time, the Conservatives justified the decision by saying that it would not be an issue because...of the introduction of the universal Freedom Pass.
That decision also rankled with county councillors and Conservative MPs and continues to do so - about a year ago, under pressure from backbenchers, KCC initiated a review to see if they could restore some limited help to pupils but again emphasised that the Freedom Pass neutralised the impact.
A working group was set up but that has not reported on options and no-one seems to know if it will.
Many parents say they would be happy if the pass could be used just for the purposes of getting children to and from school, dropping the "leisure" use element that allows it to be used seven-days a week for any journey.
KCC is unlikely to want to get bogged down in changes which could create a bureaucratic and administrative nightmare. One of the virtues of the scheme has been its relative simplicity.
Either way, the council is in a political bind and the irony is that it is paying the price not for failure but success.
