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.

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.
