that's because you get to use bike infrastructure and play by bicycle rules but not ride a bicycle. As soon as a large enough group of people did the same everyone on a bike-style coveyance would be stuck in traffic with no place to park.
Bikes are considerably more space efficient, especially since drivers have been opting for considerably larger vehicles. The same space a single SUV requires can fit 5+ bicycles, even if they’re larger cargo bikes like the one he’s riding.
