Fresh questions have been asked over the mooted introduction of 20-minute neighbourhoods in Norfolk, including whether it would restrict choice of which schools children could go to.
Norfolk County Council agreed in December to explore whether a number of 20-minute neighbourhoods could be trialled in Norfolk, although they have yet to identify possible locations.
The thinking is to plan developments so people can get to key services with no need to use a car.
But critics feared that could be a precursor to people needing permits to drive and the introduction of 'climate lockdowns', with people forced to stay home to protect the environment.
Council bosses have insisted that is not the case and reiterated that at a public meeting in Thetford - where concern has been particularly strong - last week.

But, at a meeting of the Conservative-controlled council's cabinet this week, further questions were asked about the possible consequences of 20-minute neighbourhoods - with the impact on education at the forefront.
A member of the public - Peter Lambert - asked whether the introduction of such a zone would "restrict the choices that parents will be able to make in choosing secondary schools" and reduce the right to appeal a decision.
He also asked how a choice of at least two secondary schools within a travel time of less than 20 minutes could be provided - and how that would be paid for.
John Fisher, the council's cabinet member for children's services, said the council was at "a very early stage" of exploring 20-minute neighbourhoods.
But he said: "Providing convenient and fully accessible access to schools, along with other essential services, will be considered as we explore this concept.
"Initial thoughts are there would be no change to the approach for admissions
set out within the admissions code and parents' right to express a preference for
schools. This includes the appeals process."
