That's pretty decent Uber rate (but if I had that sort of $$$, I would spend it on a decent Nuvi.) It's an overkill for the drive (oh maybe you should pay me for that scenic drive?); just check it with your Nuvi (when you're bored) Hard to believe that's an alert of that length. So how they detect "your average speed" for that long length? Camera take snapshot of your license plate when first entered and then again when exiting? Then they compute your average speed? Any periodic checkpoints in between?
