GPS Traffic Question

Could I ask you all if the traffic will update in the middle of a trip? That is, you set the trip via the GPS, then during the drive, a traffic accident occurs and this info is passed via Acuralink/traffic update. Will the GPS inform you that there is a faster route or that there is traffic on the route?

I live in NYC and traffic is a major issue...my 2013 Honda Odyssey does NOT tell me at all. It just lets me drive into the traffic, which is inane. I just need a notice that new traffic has appeared, and I can reroute myself (but it would also be nice to have an automated rerouting).


Thanks.
