I would have thought far more than 5m, given how long road spray from cars remains in the air.
We'll mostly all get it in the end, asymptomatically or not, unless there is a vaccine. It's about slowing it down, not about totally eliminating the risk.
Cycling weekly quoted 7.5m at some reasonable speed.
Even if 80% of the population do get it in the end (doubtful) on an individual level it's still worth trying to be in the 20% especially if you have any risk factors.
