Gps Satnav Connection to Proximate Stoplights.

Today I ran a long yellow light at a turn, only to stop a half block further at a solid red. Now if I'd been able to anticipate, ie by observing the traffic flow or through direct line of sight, that I'd have to stop in 10 more seconds, I wouldn't have driven through the almost red turn signal. I'd have waited at the first red light, then gone through the next two intersections in the same green light cycle. Ok. So another example. Do you ever speed on the highway, pass a "slow" driver, only to see them right behind you as you're stopped at a red light on your exit ramp. You might think, "why the fck did I drive so fast if that slow mfer is here at the same time". But I think you do it because, when you're in a hurry, sometimes you do catch that green or yellow light that would've turned red for you if you were the slower driver. And then you make it to work on time. So why not have a sat nav that can tell you what color the nearby lights are, and how much longer they'll stay that color. I believe they're already satnavs that can display live traffic data, but why not inform people about what time delays are definitely upcoming, so they can make more efficient and hopefully safer decisions when driving.
