Super close and fast pass to save exactly zero seconds

I was riding along Bridge Rd, Richmond at dusk (around 6pm). The speed limit is 40km/h and I was doing around that speed (as can be seen by the relative speed of the other cars around me) when the driver in a white sedan (rego 1SW 2TK) rushes past within centimetres of my shoulder at a speed that is probably 20km/h over the limit. And what did he save? Exactly zero seconds...he was stopped at traffic lights not even 100m further on. It was a crazy thing to do for no benefit.
Note: the video date stamp says Jan 2017, but the clock was set incorrectly - it was actually August 2021
