A controller of a motorcycle determines that the motorcycle is lane-splitting. The controller transmits a notification to vehicles in proximity to the motorcycle. In response to the notifications, the vehicles facilitate lane-splitting by the motorcycle. In particular the vehicles may flash lights to communicate that the vehicle has received the notification and will facilitate lane-splitting. The vehicles may facilitate lane-splitting by refraining from performing lane changes. The vehicles may further notify the motorcycle if lane changes are needed and the motorcycle controller may provide an alert to a rider.
