Field notes
A crew starts or joins a team on a laptop; the in-car phone needs the team code, a clear view of the sky, and power. The page says laps are queued and retried without signal, while session data stays in the browser and can be copied to the driver’s Google Drive; it also cautions that phone GPS is accurate only to a few meters.
