Tough to say in the general case, but it&#x27;s often a good idea to adhere to the so-called &quot;principle of least surprise&quot; in UX design.  If I&#x27;m riding on a trail that periodically approaches and diverges from a nearby highway, which is common around here (Seattle area), I don&#x27;t want my recorded path to snap to the highway every time I exceed 12 MPH.  That would come as a surprise -- an unpleasant one.  I&#x27;ll go so far as to say that nobody would ever expect this to happen, or be dismayed if it didn&#x27;t.<p>That&#x27;s a good reason not to include a given feature, or at least to allow it to be turned off.  <i>Someone</i> at Apple obviously thought it was a good idea, but they clearly didn&#x27;t ask very many other people, or ask any cyclists at all.
