What we do have is a pretty good knowledge of the viral load necessary to transmit the disease, knowledge of how the virus aerosolizes with heavy breathing, how plong it hangs in the air, and the fluid dynamics of how drafting works.

All of that tells you that sitting in the draft for 2 hours, with everyone breathing heavily has the potential to impose a deadly viral load. So until proven otherwise, it is onlly reasonable to conclude it is a significant risk.

A few weeks ago, no one thought that you got Covid 19 from sitting across a room with people singing. Now we know some of the most deadly clusters come from singing.

As we get better contact tracing and testing we'll know more how the virus transmits. Personally, I'd prefer to still be alive as we learn those things, rather than take poor risks that may or may not pan out.
