Or you could not race to beat a light that's already yellow. That might work too.

yellow lights should generally be three to four seconds longer

That's just ridiculous. You want to complain about how the timing only considered traffic going straight (arguably the most common pattern), but now you want to impose a timing that specifically does not work for traffic going straight? You're just going to increase the number of people who incorrectly think they have plenty of time left, and that's going to cause accidents.

Yeah, because forcing everyone to slam on their brakes all the time to avoid getting a ticket is the safest possible thing to do. *rolls eyes*

I agree. What's your point? Nice strawman. Nobody's talking about the a-holes who do this, we're talking about people driving at normal speed who see a yellow. Many of them are too short. If you have evidence to the contrary, please present it.

If you're accelerating to get through a yellow light, you're doing it wrong. Quite frankly, unless hitting your brakes is going to make you stop in the middle of the intersection or beyond, you need to be slowing down as soon as the yellow appears.

We're all on the road together. You're not special.

Yellow Light: If you *can* stop, you *must* stop. It doesn't matter if your milkshake gets on the windshield.
 
2014-05-06 04:30:15 PM  
Red light cameras only give you tickets if you enter the intersection AFTER the light turns red. Once you enter an intersection you can leave when it's safe, which is often well after the light turns red.

Here's what I learned: driving straight? Can make the yellow. Taking a turn? Then you're decelerating anyways. Treat the yellow as a red and come to a stop. No more tickets.

No. Your speed is the same (at least from a non-directional point of view) but changing direction you are in that new direction. Your net speed is the same it's just changing direction.

You are not supposed to be tailgating. You are required to leave a safe stopping distance between you and the car in front of you.

Also the system is not designed to give you a fair amount of time to stop its designed to generate ticket revenue. It works as designed

WRONG

It is very important to notice that acceleration is defined in terms of a change in velocity - not speed. This may seem like a minor point, but it isn't. Since acceleration is the rate velocity changes,

You are accelerating whenever you:
speed up - This is not difficult to grasp, since it is the common conception of acceleration.

slow down - People commonly call this deceleration, as if it were physically different from the "speeding up" case - but to a physicist, it's all the same - if your velocity is changing, you are accelerating.

change direction - This one can be tough to grasp. Since velocity is your speed and direction, your velocity changes if your direction changes (even if your speed stays the same). Since you are accelerating if your velocity is changing, you are accelerating when you are changing direction - even if your speed stays the same. Most people link acceleration with a change in speed (and increasing speed), so they think "OK, on a test I'm supposed to say that an object accelerates if it changes direction, but this is really some "fakey" kind of acceleration as opposed to the "real" speeding-up acceleration" Nope. This acceleration is just as real as the "speeding up" (and "slowing down") kind of acceleration.

Acceleration is change in velocity - which as a vector quantity means change in speed and/or direction.

Yes it does:


Acceleration, in physics, is the rate at which the velocity of an object changes over time.[1] Velocity and acceleration are vector quantities, with magnitude and direction that add according to the parallelogram law.[2][3]

From a single point of reference it does. If you are moving to point A from the north then turn west at point A from the perspective of point A facing west all you have done is accelerated.

No it didn't, and it never will, because I simply don't speed and I don't tailgate. If you drove the speed limit and didn't tailgate, you wouldn't get tickets either.

Only until they got used to the new timing.  Then they'd continue the habit of looking up from their phone at a yellow light that has been yellow for some indeterminate amount of time.  "hey, these things only stay yellow for 3 seconds.  I'd better stop" vs. "hey, these things stay yellow for 8 seconds.  Surely I've got plenty of time left."
