This is mostly a cosmetic issue, but when your rider is parked by the roadside, it will receive constant “Close the Gap” alerts when other riders past closely. There’s no real reason to get those alerts as other riders pass, if you’re not actually moving.
If the rider is traveling at 0mph or has a foot down (or however you determine a rider to be “Stopped”), the alerts shouldn’t be shown. The sound is similar to the disconnect warning and popup messages, so it can be distracting if you step away from the bike momentarily and hear them come bleeping in.
