Whatever algorithm they use is sometimes a bit too greedy. There have been times where I've been able to manually drag my path to another freeway and make it faster
What is weird, they even don't follow easiest to calculate path. Let's say there's an officially signed route following top-tier highways. Nope, it's suggesting a random dirt road. I'm pretty sure it'd be easier to hardcode the "official" routes and then check alternatives whenever there's a problem (crash, slow traffic, etc) on it. Nope, "official" one is all green and no constructions and crashes. Yet it's still suggesting the random dirt route :/
