I wouldn't judge anyone's decision on this one way or the other, but when I am tempted to go out on a ride I think about a few things:
1) Right now the positive Coronavirus test results are at about 7-8% of those tested. So whenever I go out I figure for every 100 people I encounter, 7-8 of them may have it. Which ones? Nobody knows.
2) How bad would I feel if I went out on a ride, and against the slimmest of odds contracted the virus, brought it back home to the people I love most, and one of them gets sick, or even worse dies from it. I am sure I would hate myself for the rest of my life, and it would in no way have been worth a trivial motorcycle ride to me in hind-sight.
3) If I go out and against the odds have a get-off that puts me in the hospital, I would not only be potentially consuming medical resources that could otherwise be spent treating Coronavirus patients, but I would also be exposing myself to the Coronavirus by being in a hospital setting. See No. 2 above.
Anyway, having said all of that, I can't say I absolutely won't go out on a ride between now and the end of our WA State shelter-in-place mandate, but when I think about these things it certainly curbs the appeal for me.
