> I think Google uses phone sensors to tell motorbikes apart form cars

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.
