I notice this from within a car as well. Cars take forever and waste so much space taking turns, merging, switching lanes. The issue seems to grow exponentially with vehicle size as well; nippy small cars turn and navigate a lot better compared to American genital compensation trucks.
Even cycling into the city from my neighbouring town (~10 km) can be faster than a car at peak rush hour, because city traffic is just an absolute gridlock (this is in Galway Ireland, the traffic of which is notoriously bad even by Irish standards, but still).
