Lets face it these things aren't bolted onto big lumps of foam rubber, remove the bullbar and the discovery will still flatten anyone it hits.(you'll just have a dent in your bonnet)
Oh yes I realise that, I'm not thinking of the man walking across the road, he's flattened either way, more of if you hit another vehicle.
Oh yes, i agree there, they will do more damage to your own vehicle than they save if you hit another vehicle.
