Yesterday I had an appointment in my calendar for an event 100 miles away from my home, and the roundtrip there had me crossing 10,000 miles in the odometer. Next to the appointment in the calendar was a button with a phone icon and "10,000" next to it, so I wasn't sure what that meant or if something was going to happen when I crossed that threshold. Alas, nothing unusual happened during the roundtrip. Has anyone seen this before? Does it have any particular meaning?
