There was many funny ideas starting from tuk-tuk bikes and ending with spaceship, I liked them a much.
Anyway I suggest keep Waze map simple and clear! If there is power for software development - we have lot of good ideas in Waze forum.
IRL case: Accident on freeway, traffic jam and what did truck drivers? They tried to use smaller alternative roads, but as they cannot drive on ice and snow, they blocked roads and collapsed all rerouting system for normal cars. Trucks just cannot drive on snow and ice if they do not have winter tires (M+S)! Of course situation in countries is different, but s-t happens. Truck routing is not easy!
Please remind also that 99% of new trucks have their own navigation systems from factory!
