My Z is parked on the street so that is the only place i have to wash it and I have done so twice during lockdown. No one has said anything negative, only positives. I have been careful to keep an eye on people coming down the pavement and myself moving out into the road for them to pass if they haven't crossed the road already. Luckily its quite a quiet road so this isn't a problem.
Berate me if you will, but I won't be stopping it (I'm by no means a detailer so just wash and dry for me). I already can't dive with my own personal air supply which is one of the only things I enjoy. Yes there is the possibility of an issue, but as others highlighted, so is there with DIY, running, cycling etc and don't want to stress the local hospital which is currently at less than 50% capacity....
Can you tell I'm a bit bitter about it?
