the issue with that is if it’s ok to go to the park, which is in direct conflict with the stay at home advice, then how many are allowed to go to the park, and how packed do you think it would get? It doesn’t take a rocket scientist to see how it would end... gove an inch people take a mile... so the rules are in place, they don’t say you can’t go out, just limit it to 30 mins for exercise, exercise is not sunbathing
sadly idiots are still taking a mile while 90% of the public are doing there bit, if it was easy and people would be responsible for themselves there wouldn’t be a lockdown, look up Matlock bath the Sunday before lockdown when the advice was still in place to stay away from each other and you will see why people can’t be trusted and the lockdown is in place
see attached pics for Matlock bath (bikes pic) when advice was stay at home and the 2m recommendation was not law, and the actual pics of the park from the weekend vs the dream land where everyone is 2m apart...
