You might check and see what settings you have for traffic delays. If you try different times from 2 minutes, 5 minutes, 10 minutes, etc. you might find that it would route you around that 15 minute traffic delay. When driving back from the eclipse, my car's navigation tried to route me around two delays. I followed the directions for the first delay and was routed to a virtually empty highway where I only saw 5 cars in the 30 minutes that I took the alternate route. It was
a lot less stressful than the interstate that was
packed with returning eclipse viewers who were all headed home at the same time and helped me avoid an accident where a semi had flipped over onto a car, backing up traffic for miles. I actually made it to the next Supercharger before a Model X which left the previous Supercharger 15 minutes before I was finished charging. A couple of hours later, my car suggested another alternate route but I didn't get off the interstate in time and ended up spending nearly 20 extra minutes in stop and go traffic.
I almost ALWAYS use the nav to go to work because there are two very different highway routes that are pretty much a wash unless there is an accident or traffic. The GPS knows about those and I don't. I ignore it at my peril. It also predicts reasonably well my arrival time whichever way it routes me, and I like knowing that.
The very first time I drove my car to work, I used the navigation and it routed me a back way. I thought it was odd but when I got to work, I found there was an accident that had virtually shut down the usual route and caused delays of an hour for a 5 mile drive. I don't always use navigation for my commutes, but when I do, it routes me around traffic.
WAZE app is awesome. I wish the Tesla/Google nav was Waze instead
I've never really liked Waze. Whenever there is an accident, it shows me 4 or 5 accidents along the same 4 mile stretch of highway. While there could be more than one accident, I'm pretty sure there aren't always 4 or 5 of them.
