Like it makes a difference if metal or plastic hits a pedestrian if a 5,000 pound vehicle hits you. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> What's up with that?

I would love to see some photos of the secondary damage on the rigs they were bolted too.. That plastic bar looked pretty good after a 20mph tree hit.. (plastic can be damn tough if it is used corectly)

Can a winch be attached to it? <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> Well, this is crap. What I'm sayin might be a little shocking but my truck is my castle and I want to be safe in the first place. I don't think about other cars' safety, this is their problem... It's obvious that a tree wins with any vehicle, but most of the accidents are due to the reckless driving of other people and not reckless trees running across the road. Whether you have a bumper or not, it doesn't change a thing because your stiff frame is the cause of enormous forces during a tree collision. But during all other collisions your mass and a strong front make you a 'winner'. I'll stick to metal...

Regarding getting hit with 5000 lb of plastic or metal. Its not entirely a good analogy, but if you had a choice between getting hit with a 5000 lb concrete block or a 5000 lb sack of styrofoam peanuts at 40mph which would you pick? Until someone gives me good reason to do otherwise, I'd take the peanuts. They would "give" and absorb some of the shock unlike the concrete block which is going to make me do all the "giving".
Getting hit by a vehicle isn't good any way you look at it, but the steel bullbar is apparently a lot more rigid than the plastic and certainly a lot more rigid than the original sheet metal. The more rigid the vehicle, the more damage its going to do to the pedestrian in a typical situation where it doesn't literally run over the person. Plus, the pipes on the bullbar are going to concentrate the force more if you hit them.
I read somewhere that some of the european countries were considering bull-bar bans because of the additional injuries they cause to pedestrians.

Ennnhhhh, I donÆt know about thisà Composites have come a long way in the past 15 years or so, but polyethylene has some inherent problems to it that make it unsuitable for impact protection, particularly in a ôlife criticalö function. In addition to itÆs relatively low tensile strength (but high ductility) polyethylene has serious issues with UV degradation, even the ônewö blends that are treated to resist.
IÆd like to see a cross section examination of this bumper after impact testing, my money is on serious delamination / molecular structure change at the impact line. This would cause the same issue as a steel or aluminum bumper under similar impact situations, replacement to assure safety. Bumpers ainÆt nothinÆ to mess with in regards to the safety of you and your vehicles occupants. From an engineering standpoint, this thing is a nightmare.
What the hell is this ôpedestrian safetyö thing? The only ôpedsö IÆve ever even come close to running over are the street people that walk out into traffic looking for a handout (I avoid that, messy situation creaming anyone with a vehicle).
Jeez, IÆd be laughing my ass of right now if I wasnÆt concerned that a company is passing off something as ôthe newest, best safetyö dealà <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I was working in Sydney, Australia 2 years ago and they are having a big heated debate over the bullbar issue down under. The big metropolitan areas want to ban them as they say that the bars kill too many pedestrians. I can't really figure out the logic though. I think if a car even without a bumper was going 30 mph, chances are that the person you hit will die. The thing that the opponents are saying is that the bullbar forces the person under the vehicle instead of over the hood. Anyways, I don't agree with the opposition because I could never find a real credible study if bullbars kill more than just a bumper. They always seemed to compare cars with trucks instead of trucks with bullbars vs trucks without bullbars. This way they could make it look worse for the trucks. The whole plastic issue came out as a compromise. The problem is that you need real bullbars when you get out of city limits and are in the outback. What are you supposed to do when you get back to the city, change your bumper from steel to plastic? The roadtrains (big trucks) deliver goods and drive across the continent to deliver them and the cities want to ban them from having bars. Obviously, they are fighting it since most of their transit time is spent in the outback where Roo stikes are a very real problem. Funny thing is that Australians make some really cool off-road gear and now they want to ban it. This fight I think will be dragged out over a long period of time. Someone from Australia correct me if I am wrong.
