Well, just returned from having the 911 MOT'd (passed) followed by a glorious drive back. Roads are reasonably empty except for the number of lycra glad cyclo's - more of them than cars. So it seems self isolation whilst pursuing your hobby is fine as long as it does not involve burning fuel.

Add to that the runners and walkers I came across and I felt quite justified in taking the scenic road home.
I know the mantra is 'Stay at home' and the Government is not going to make an exception for classic car owners but fine weather, 1960's levels of traffic and petrol at a £1/litre make self isolation on four wheels with the roof down a joy.
So providing I am not putting others at risk I will be enjoying my cars, something I judge as being necessary for my well being in these dark times.
