Similarly I think people should consider the risk to others if they get this pathogen rather than just the risk to themselves.
The solution is to get rid of cars as a primary mode of transport, and I really do think we should do that!

This really isn't remotely analogous, particularly since you absolutely can know you're at risk of spreading COVID.
Your version applies to cars too! By driving a car, you are at risk of causing a car crash!
With COVID, you can. Pretty easily.
Certainly, anyone who receives a positive PCR test for COVID should quarantine ASAP. But if you're incubating COVID, but not infectious yet, the tests will return negative. A test only tells you whether you were infectious at the time of the test, so by the time you've seen the results, the information is already outdated.
No. That wouldn't be a particularly useful statement.
Dismissing the aggregate risks solely based on your own is short sighted.
