Exactly - people want to see all this data
Yes (well, some).
and have Google log/display it.
Why do you think we (or anyone) want Google to log it? That is not needed, if I want it logged I would GREATLY prefer that be done by a local app of some kind, where I control the data from it directly.
I can imagine future politicians, where it's leaked exactly how many times the driver of his car went over 75MPH... as just one example why not everyone wants Google to log it.
