If you watch, the black SUV *speeds up* to try to make it. You can also see the drivers side airbag go off.

That's more than slightly funny, that thar is hee-larious. Too bad a kid may have potentially been hurt though.

The posts stop moving upward as soon as something hits them. That sounds like a safety mechanism to me. Unless you expect them to be intentionally ineffective and break when a car hits them?

These are the same type of idiots who would speed up to run a red light, putting everyone else's lives in danger. They are deliberately irresponsible drivers and they deserve whatever damage happens to their car or body.

Okay "no functional safety mechanism" (and since we're splitting hairs: how are the cars lifted off the ground by a pole that isn't moving?) Which part of my post did I suggest that? Oh that's right, I never did. You're just making stuff up.

No, I was asking. Hence the question mark. Let me rephrase: Please explain clearly what sort of safety mechanism you expect them to have.

Are purple monkeys flying out of your ass? Nothing to date has suggested this, I'm simply asking. With a question mark.

Instead of the cars being rudely and suddenly stopped, the thing should create some sort of bouncy ramp, so they're comically catapulted into the air.

I'm not a traffic engineer, so it isn't my job to figure this out. The design of these mechanisms looks dangerous.Okay, sometimes an "armchair traffic engineer" has the best ideas. I stand corrected.

No, I'm wrong, it should be a MOAT. To let the bus pass, a steel bridge drops down. After the bus has gone, it opens to a 15 foot long, four foot deep pit of water. The beauty is, the lift for the bridge doubles as a crane to pull the vehicle out in 15 minutes.

Okay, to clearly answer the questions you've asked: 1.) No, purple monkeys are not flying out of my ass, 2.) The cars are lifted off the ground by their own forward momentum as well as the slight continued upward momentum of the pole in the fraction of time it takes to register that something has hit it, and 3.) You never suggested my sarcastic description of a possible safety mechanism in your post; I posted it to express how I found your post to be lacking in information as to what your opinion is:

I swear to God I'm not trying to put words in your mouth, I'm trying to understand your point in making this statement. So let's back up: Do you believe that the poles should have a safety mechanism, as you noted they do not?

Not punitive enough. They should have a 60 second timer before the car is crushed into a 3x3 cube.

In 60 seconds the car couldve passed by then.

no no, I don't want to get rid of the posts. They are for holding the car there until it can be crushed. Obviously the people inside fancy themselves as speedy, it should be plenty of time to get out.

crushed? Did I miss something? ..

I think perhaps yes.

Time to go watch that video again..
