The current scaling logic in the code for link_vehicle_counts here is designed to handle cars and PT modes.
This leads to issues where non-PT modes such as bike, taxi, and walk are not scaled properly.

scale_factor = self.config.scale_factor
if self.mode != "car":
    scale_factor = 1.0

We observed that modes for bikes are not scaled. And non-public transport modes (including taxi, bike, and walk) should be appropriately scaled.

It may need a better name for the event handler e.g mode_link_counts if we would like to use this to get the links count for other modes.

When vehicle_link_counts produced the link counts output for taxi, it seems wrong since all the counts are equal to zero. Worth to check the logic for non-car mode.
