But wouldn't that other car be classified as error?

I don't know what the tipping point is, but it'd probably take more than one. I've commuted through backed up/stopped/solid red sections on a motorcycle where I just get to lane-split and cruise through, and it'd still stay red.

I think Google uses phone sensors to tell motorbikes apart form cars. Pretty simple tech: cars don't lean.

Which makes it all the more infuriating that Google Maps still has huge flaws when it comes to motorbike navigation.

While they could, I doubt they do... do you have evidence of this?

not the GP, and I don't how it's done, but my Google Maps timeline does distinguish between motorcycling and car trips, however its reliability is questionable. It has often mis-categorised my motorcycle trips as car trips, but rarely if ever the reverse.

I would guess (unsubstantiated) that it classifies a motorcycle trip as being unexpectedly fast through many traffic jams.

They are pretty good to identify public transit from cars too.
