If the radar drops, the safety strip shows it. The system reconnects in the background. Red covers both a closing vehicle and a lost radar. Either way the rider is without rear awareness.
Tunnels and dense buildings degrade GPS. Turn-by-turn pauses and falls back to dead reckoning from the last known position. Speed and trip stats keep running locally.
Warnings escalate twice. At 20%, amber shows remaining ride time. At 5%, weather and air quality drop off; navigation and radar stay on.
More than 50 m off the planned route, Verro recalculates quietly. An amber banner notes it; the dashboard carries on.
In bright sun, brightness and contrast boost automatically. In rain, touch input pauses and the cockpit goes glance-only.
