Several cities in Brazil already have traffic lights that indicate how long until the green lights.

Turning the engine on and off all the time is a terrible thing. It actually consumes more fuel is the car is to be left off for less than45 seconds. Besides, starting the engine puts a lot of load in several components, because static friction is a lot higher than dynamic friction.

The chances of engine failure when the car is being turned on is much higher than when the engine is already on. Thus, if people is to turn off and on their engines at traffic lights, what we'll see is a lot of people with broken engines at stop lights.

I do, however, like the idea, because I can relax for a few seconds, knowing exactly when I'll have to be in the "ready state" for the green light.

This was one of the worst posts at Neatorama ever. Terrible. Totally waste of one's time. Not fun, not informative, not clever.

Hmmmm..... nacho and dandruff...

That was my watch! I lost it a while back while fishing in that area.

May I have it back, please?

That fish isn't gonna last long... maybe just enough for the photo to be taken.

Liquid nitrogen is pretty expensive and vaporizes really fast due to the much higher ambient temperature.
