And the way how it works is pretty cool, since it color-codes them according to rules which i assume are based on closing speeds/gaps estimation.
It is basically soft-AI applied to your run-of-the-mill rearview camera, like one step up from the outboard rearview mirrors indicating traffic the car can sense by distance sensors or radar.
Especially with the blindingly bright lights you can see in these shots, the arrows indicating where the car is does give the driver a real advantage over those who haven’t got such a system.
