Google Maps

[KungFooBob]

Just sent me a notification asking if I'd like to review a trip I made on Sunday.

So I thought I'd take a look.

It says I did the first part of the journey (to a bike clothing shop) by motorcycle, then the 2nd leg (to the sea side) by car. Then it suggests I used a motorcycle for the trip home.

It's obviously wrong about the car bit, but how the fuck did Google maps know I was riding a motorcycle?

I think I read somewhere that your smartphone knows what angle you're at. So going fast at 45deg indicates you're on a bike rather than a car.

If you were using google maps as sat-nav at the time, then it might have been recording the leans relative to horizontal (which the phone will be able to measure) and then making a guess.

Presumably on the middle bit you rode like a newb.

I had the phone in a mount that a attaches to the factory satnav bracket, in portrait.

I didn't use maps for navigation, I put the phone in the mount just incase!

If the GPS aerial is on,then google will still be recording your position.

This is because
a) they want to sell that info to advertisers,
and
b) there actually ARE people who seem to want to have that history for their own perusal.

[KungFooBob]

Yeah, I have location services enabled, I like looking back at where I've been, I'm just surprised it (almost) knew the difference between a car and a motorbike.

Prolly notes the vibrations.

Shirley it will identify 'down' as a line through [combined] centre of mass to tyre contact patch? So won't be able to determine lean angle.

I dunno, but I noticed the same as Bobz (google knows when I've been motoring / riding / running / walking) because it sends me monthly stats.

nope - orientation of phone relative to force of gravity (using tiny assemblies on the motherboard), Or - more complex, but mathematically possible, (I think)... orientation relative to line from current GPS location (derived from satellites) to centre of earth, with relation to multiple GPS satellite signal sources. Remember there's something in the phone that "knows" it's orientation relative to the earth : which explains why some photos end up being the "wrong way up" sometimes - eg when the phone is oriented slightly oddly when the photo is taken.

You should put the phone in one of those remote key hiding bags; and if any room has a tv in it, always walk out of it backwards.

TBH I didn't know that phones have a gyro.

4:00 onwards



With the 3-axis sensors, provides the info. Probably. Perhaps ...

And leads to the conclusion that, during the middle part, OP was riding like a wuss

[Mr. Dazzle]

I'm gonna sit in the passenger seat of my car making brum brum noises and leaning like I'm on a motorbike next trip...see if I can fool it.

Surely it must be pretty easy to work out car Vs bike based on location & speed, especially if you are filtering / overtaking traffic, no?

That would be my thoughts too.
