This behavior is consistent with all my other nav devices - iPhone, 3x Garmin, etc. They all seem to look at distance, speed and make a simple math calculation, but consider intersections as “interchanges” without traffic control devices. So if I were to obey the GPS directions, I’d go .6 miles less, but more distance is spent in 25 mph or stuck at the long light than if I go the slightly longer way, where one of my right turns is at a stop sign.
The GPS mapping is often not cognizant of “long” traffic lights, intersections with no right turn on red. This morning, I tried to figure out why this happens. I used Garmin’s basecamp to play with the 2 mile stretch from my house to the US1 intersection.
short way is 1.8 miles and 5 minutes. 3 traffic lights this way, one of which is the long “left turn” light.
My preferred way is 2.1 miles and 4 minutes. One traffic light this way, that no matter how hard you try, you almost always miss. Still shorter than the light going the other way.
My preferences are for the faster route. Every nav device I have makes this mistake, not just the Raptor. I just happen to know about it because the routes are familiar to me. I’m sure the nav programs do this everywhere.
