Can a 35cm bollard stop a truck?
 

Well? What do you think?

Those black bollards, with yellow stripes around the top, that go up and down.

Do you think that's enough to stop a truck filled with explosives travelling towards it at high speeds? The goverment seems to think so... don't know why.

I've seen videos of something like that on the discovery chan or TLC. The truck gets fucked up, the pole needs new paint.

More or less, yes. And the bollard still goes up and down afterwards.

I've never seen a bollard in real life. It's a nice concept though, I suppopse. Better than what we've have wich are usually similar to this

Really? Well knock me down with a feather. We can't go anywhere without seeing bollards. :p

Lenny, how have you been?

I've read the postes above and have learn't that some people needs to learn how to spell.

Looks like you have all of us beat.

Srry maam. I'll go buy a dictionary asap.

I've seen those things. I'd love to see one used properly on a speeding vehicle.

they should put remote controlled ones on highways to pk stupid criminals and the elderly.

Nice.

You'd also have to spring load them too so they jump up in a second - do you think that people, even if they are speeding or elderly, won't notice something a couple of feet high extending out of the ground in 30 seconds?

Pneumatics. It'll have no problem.

Air gun type?

Air ram!

Haha time it right and punch it up through the floor of a car right as it drives over the bollard.

You know, there used to be things that you can buy to stop burglars:

Little spikes that you put under your seat... well I say "little" - they're a few feet long. As soon as someone sits on the seat activating the pressure pad on it, the spike punches up through the seat and, well, you get the picture. But, of course, there's a little code box thing that you enter a code into to turn the spike off. Therefor, a car theif who doesn't know the code, or that the spike is there will sit on the seat and BAM! Instant Kebab.

Holy fucking shit. That's intense.

Wow, so that's how you do it in Britain... :wierd:

There was some british invention that has flamethrowers underneath the handles that one can activate if smeone is trying to enter their car
