Or, just calculate it?

Car contact patch is 4 x 160cm2. https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=... Car avg. weight is 1800kg. https://www.bankrate.com/insurance/car/average-car-weight/

Pressure = 28kPa

Human is 100cm2. https://en.wikipedia.org/wiki/Pedobarography Average human weight is 75 kg.

Pressure = 8.5kPa.

So it's simply not true what you say.

Compare that to a road where the truck literally forms grooves into the asphalt. It ripples like the viscous material it is in those conditions under multiple tons of weight. An intersection by me looks like its plaid with the grooves from perpendicular trucking traffic. And cement roads do last a long time but they aren't indestructible. I live on one. Trucks damage them and crack them up over time and the city has to fill in potholes. The more construction going on the more damage. Any big apartment build just destroys the concrete apron and sidewalk on the lot with the equipment because its that heavy. Orders of magnitude heavier than any human on a bike can be.
