Never used this. How does it know you are walking? I recently walked 4 miles in London faster than cars in the traffic jams. And driven miles in a motorway hold up at a steady walking pace . How does it know you are on a bus,not in a car. I have searched google routes in the various modes and then followed them in that mode. But if you need to remember to set the correct mode every time you pop out to the local shop it it may not stay accurate or relevant. I might have run a marathon and had it recorded as a car journey. No proof I ran , other than my being dead.
I also dread the day I go to a shop and a display or computer speaks to me " 'Welcome Lord V. We havnt seen you for 7 days ,3 hours 15 minutes 42 seconds . Google says you must need milk so this will automatically be charged to your google account. If it wasnt you 7 days ago, or you do not require milk please enter the code we have sent your phone "
