I'd love for the horn to have more purpose. So lets say I stop a vehicle, and don't like where they parked, I'd just have to honk my horn twice and they'd copy my vehicle movements. So If I drive forward, they also drive forward. If I pull off to the side, they pull off to the side. When you activate this sequence, the chevrons above the vehicle would turn green, indicating they are copying your vehicle movements. To deactivate you'd honk your horn once, and they'd stop there.
