@StormyClouds Yes, it probably is safer as far as being in contact with other people is concerned, but the fact is it's an unnecessary journey and all journeys, necessary or unnecessary, involve a certain amount of potential risk: breakdown, road traffic accidents etc.
The government doesn't want people moving around too much from place to place, spreading the virus, potentially having accidents and needing the use of already stretched NHS resources.
Rules have to apply across the whole country and they have to apply to everyone's journeys.
Essential travel, means essential travel, whether someone lives in the middle of a city or a ten minute drive away from a forest.
Forests and other such places in the county I live in have shut their car parks for this reason and have put out message for people to stay away and not park in the streets around the forests, which is what's been happening.
Far from their journeys being harmless, people are causing massive problems for the local people.
The same with seaside towns, they want people to stay away.
