I like to frequently check out the alternate routes on my drive to check the various ETAs, so I usually start my drive by checking alternate routes and then usually just picking the fastest one. I know that if I just click "Go", it will probably pick the fastest one for me though.
However, I have yet to have Waze automatically change my routes once I start. This morning, I saw traffic was building on the interstate where I usually get on, so I took a look at the alternate routes. As I expected, the alternate route was a few minutes faster, so I chose that one instead. My question is, why didn't Waze automatically change my route? Is there a certain threshold? Maybe it won't automatically re-route if it only saved me 3 minutes or so?
My other question is, if I go to the alternate routes screen and choose a route myself, am I then "locked" into that specific route now, regardless of traffic? Or will it still attempt to route me around traffic if needed?
