This depends where you are, I suppose. Fire Brigades in urban areas typically dispatch two engines that take two different routes to ensure one route is not congested, and at least one engine is on a faster, if not shorter, path than the other. Even real-time route planning cannot mitigate an unexpected cause of congestion yet to occur. Depends on area. Dense urban streets where contagion of fire may require this while a remote home in a rural may mean this route mitigation isn't necesary. However in both and all cases a rapid response is needed as lives are at risk.
