I just got Waze. It doesn't seem to work on my computer but it kind of works on my ipad. At first it told me I couldn't drive to my location - then I picked a larger city and it was fine with that. Then it told me that one route through PA (76) had $11.00 in tolls and the other (80) had $56.00 in tolls - is that right?
I was very slow to accept Waze, and very skeptical about it; what do I need a GPS program like this for when I have GPS in my car? Once I started familiarizing myself with it, and realized how reliable and versatile it is, I found myself using it all the time, even for relatively short trips.
Like any other GPS system, you can set Waze to calculate distances and speeds in English or metric measurements; you can set the language it uses; you can direct it not to use toll roads, or bridges, or tunnels, or highways; you can have it speak all directions to you; only warnings; or nothing at all.
But unlike many other GPS systems, Waze constantly tracks traffic conditions in real time, and will update or change your route as necessary. Miles before you are aware of an accident, or vehicle fire, or police incident, that's delaying traffic, Waze will calculate how to get you around it. (Sometimes, it will direct you to an exit or route that doesn't seem to make sense, until you realize it's detouring you around something.)
Waze will warn you of speed traps, roadkill, debris in the road, and stopped vehicles ahead well in advance of you encountering them.
It calculates tolls along your route, and will take into account your EZ Pass transponder if you have one. (And yes, it's accurate.)
Waze works everywhere; I use it in Europe, and it works there just as well as it does here. (I set it to metric measurements there, of course.)
I have not found a downside yet to Waze over several years of using it. Download the app to your cell phone, get a good phone holder for your windshield or dash (Andobil's holders, sold on Amazon, are perfect IMO) and enjoy...
Good luck on your drive...have a nice trip!
