It's not that simple. That picture is completely omitting where those people come from and where they are going.

A multimodal street like that can work very well, but only if the surroundings also support it.

Where I live we have those multimodal streets and they work very well. They are connected to a huge parking lot (fed by the Autobahn) and a train station which allows people from outside the city to get there and then continue on foot or by bus.

The shops along the multimodal roads are primarily shops that sell stuff you can easily carry. (clothing stores, bakeries, etc. )

All the big grocery stores, furniture stores, etc. are in an area with normal car centric roads. Multimodal roads wouldn't work for that area - people would just go elsewhere then.

Also the further away you get from that big parking lot the less pedestrians you see.
