I have an Android phone and use the Google app &quot;My Tracks&quot; to record walks I go on.  Sometimes the rate that it tells me I&#x27;m walking jumps wildly high, even though I walk at a very constant rate.  Sometimes it&#x27;s 2x what it really is.<p>I would hate to be a good driver and be penalized for bad software&#x2F;hardware.  Given the track record of the auto companies (on which the insurance companies will rely), I think it&#x27;s a given the software will be really shitty.
