When the person I was responding to said "Not taking the vaccine is a substantial risk", I believe they were referring to the risk to the person not taking the vaccine.
That aside, driving a car, even with a license, is a non-trivial risk to others, possibly the greatest chance the average person has of killing somebody, so I don't see how they're not comparable. Moreover air pollution kills seven million people worldwide each year, which everyone contributes to when they drive, and that's way more than covid19's killed.
