Roadside camping is, and will become an increasing, controversial topic as lock-down eases. There is significant animosity from locals, and its almost certain landed interests are planning a campaign in conjunction with their friends in the media to apply pressure for change. Local Councillors are seeing this as an opportune issue to get involved with for votes. Hill-goers, locals, land-owners are all fed-up with the roadside Ned element.
I'm not suggesting that you would behave in such away, but most hill-goers would be very reluctant to promote any roadside camping at the moment, as even if done responsibly the pressure of numbers is going to lead to potential conflict and increased resentment / stereotyping. Pick a Glen, a Glen with a loch about 4-6 miles from the road, away from estate buildings and walk up it, its unlikely you won't find somewhere to pitch. Obviously don't leave litter and even though its permissible given the current sensitivities don't have a fire.

They see the problem element of roadside campers and the public's revulsion as a way to achieve this.
