A hypothetical, hair-splitting, nit-picking technique question, inspired by Newton's thread -
Idea for government: Traffic Light Timers
Here's the hypothetical situation (OK, this actually came up for me last week). What would you do - assuming your goal is maximum fuel economy?
The scenario:
You're alone in your lane (nobody close behind), in a med/low speed glide approaching a stale green light which does NOT have a pedestrian count-down timer, or even a walk/don't walk signal.
You think the light is controlled by sensors for cross traffic. There's a vehicle on the sensor. In other words, the light
may change at any second, but you can't predict when with any certainty.
Your options:
1) throw in another pulse as you approach the light, and hope you make it through on green;
2) continue gliding down, considering that if you
don't pulse, you'll more or less roll to a stop at the light (which may still be green when you get there);
3) some other option?
