Car Accidents & the Unvaccinated?

Looks like this is where this headline on the unvaccinated and car accidents has come from. Quote: Our theory is that an adult who does not follow public health recommendations, may also not follow the rules of the road. If ever there was a strong thesis, this is it😳

I have questions:

1. Apart from Sunnybrook, who else funded this study?
2. Vaccines have only been made available since 2021 for C-19. How is this enough time to make this correlation?
3. Seeing similarities doesn’t equate to a correlation or causation, does it?

*Note that pitch to insurance companies at the end😳
