| Jan 5, 2012 at 22:30 | comment | added | finnw | My car has a turbo diesel engine & it's nice to have those 2 seconds to rev it. If I didn't then it would be slower to start than a petrol engine. | |

| Dec 31, 2011 at 12:34 | comment | added | Lie Ryan | @djeidot: that means you'll have to be fully concentrating at the light the whole time or you have to be familiar with the light timing on the intersection. If you have yellow (amber) between red->green light, you have time to relax for a while with your hands away from the wheel and your breaks engaged; with sudden green you have to be prepared all the time (lest you be caught surprised by the sudden change). | |

| Dec 31, 2011 at 1:22 | comment | added | djeidot | Well, I'm used to the sudden green. You don't need a yellow light to prepare your car to go, you prepare it on green. What's wrong with that? I have my doubts on whether that makes so much of a difference in traffic. | |

| Dec 30, 2011 at 18:51 | comment | added | user606723 | Whatever the reason, I wish we had this in USA. I am tired of looking at the side to look for when the crosstraffic light has turned yellow. Do I need it? No. But if you're impatient it's a nice FYI. | |

| Dec 30, 2011 at 15:47 | comment | added | dbkk | It might be the force of habit. A few decades ago, when less-reliable cars were abundant, a few seconds notice was useful to let the driver rev up the engine and shift into first gear without stalling. Sudden-green creates an unwelcome sense of haste if you're driving a jalopy. | |
