Will it really help and is it worth $499 per 18 months?

First, when you’re stopped at a red light, the car displays a countdown to when it will turn green, which takes away the sometimes frustrating uncertainty and allows you to make better use of your time than staring at the light in anticipation. The timer turns off when there are four seconds left to encourage you to reengage with the road ahead as the light goes green, so you don’t run into anything when you do.

I changed my mind on this - see post #10

Then, when you’re on the move and approaching a light that’s about to turn red, TLI calculates the exact speed you should be driving to make it ... without breaking the law. If it doesn’t think you can get through safely, it warns you to start slowing down so you can stop in time, instead.

It takes some of the fun out of trying to time the lights yourself and cruise on through without getting held up, but can be more effective since it’s getting tipped-off. Along with reducing travel time, Audi says less stop and go driving should save some fuel, but you do need to pay for an Audi Connect Prime telematics system for it to work, which costs $499 for 18 months after a six-month free trial and comes with a suite of connected services.

Seems like a cool thing to talk about at parties but prolly not much help in the real world.
