I did $15k worth of damage after hitting a roo...............WITH a bull bar! My vehicle was drivable, and got me safely home. Irrespective of how late a model vehicle you drive, a bullbar WILL save your skin in an animal strike.
Oh, that's right, all livestock including wildlife live behind fences.............. 
Hi Dr Evil
Sadly you are incorrect when it comes to the vast majority of new vehicles. A bullbar spreads the impact load across a wider area of your vehicle reducing the crumple zones efficiency. In an offset collision, the most common 'head on' style impact, the bullbar robs the vehicle of the ability to crumple as designed. Now here is the kicker. Its in the big hits, where the chance of living or dying is in the balance, that the ability of your crumple zones to operate as designed may just save you and the other occupants. The crumpling of the bumpers, mudguards, inner fenders, bonnet, radiator, fan, fan shroud etc etc all slow down the actual stop that kills you.
The bullbar prevents this and spreads the load out across the whole front including the opposite chassis rails and you stop quicker. Not what you want. Survivability is huge nowadays with crumple zones and airbags and its often the cars that look terribly damaged where the driver has survived due to the crumple zones doing their job.
This is not to say, and I dont suggest it for one minute, that no one should fit a bullbar, it just needs to be thought through. If in your case a disabled vehicle may be life threatening (thats how I read what you have said) then it makes sense. If you live in an area where you travel at night and the chances of hitting wildlife is high then again it makes sense.
However, if you live urban and/or having a disabled vehicle is not a life threatening issue, then the decision does not make as much sense. A good example is I lived near South West Rocks for 5 years and travelled into Kempsey. In that time I hit a wallaby that did a bit of damage. Had I had a bullbar no damage would have occurred. But had I been in a vehicle accident on the highway then I would have been in a safer position.
Hope that makes sense. Not talking about banning bullbars or such sillyness. Just that its worth thinking about, particularly if you have your family in with you.
Cheers
