How strong are bull bars

if you look at the second page i think of my thread about me hitting a deer, you will see a picture of a guys truck when he hit a deer at 35 mph with no bullbar, he got alota damage
My bullbar took the full blow of the damn deer, it pushed the deer down and away from my truck, i mean its not like the bullbar is welded to my truck, its gonna move, the same would happen to a brushguard if im correct

 

He got no damage cause he has a heavy duty bumper, he didnt buy the thing so he could find deer and mow them down. i just gonna say it, i think those bumpers are just ugly and worthless if your not gonna off road with it. im not gonna drop a shit load of cash for an offroad bumper when i dont offroad, only reason why someone would need them for everyday use is if they suck ass on parking and hit cars alot. sure those bumpers might be impervious to deers but hitting a car head on or a tree will result in damage, so those things aint indestructable
