Come on - obviously bad driving is not primarily an infectious airborne pathogen. Bad driving is something you can unilaterally inflict on other people to permanently ruin their lives, as is an infectious airborne pathogen.
Indeed, driving lorries and buses requires an advanced license, with far more stringent testing, presumably because, like in the analogy, you could kill a lot more people behind the wheel of those?
The problem is, 73% of drivers think they're above-average drivers[1]. So just as you can't know whether you're the one spreading COVID, you can't know if you're the bad driver.
The solution is to get rid of cars as a primary mode of transport, and I really do think we should do that!
Sorry, I might not be understanding where you're going with this. I initially thought you meant "you can know you're at risk of spreading COVID, because everyone is at risk of spreading COVID."
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whether you were infectious at the time of the test, so by the time you've seen the results, the information is already outdated.
Bad driving begets bad driving.
Some jackass cuts you up dangerously, your adrenaline is pumping and you then follow too close behind a third driver repeat ad nauseam
