Not entirerly true
ADR compliance also includes crash testing to ensure air bag activation is not effected.
You can actually have a bullbar that is too strong. In that case even small hits to the bullbar will fire your air bags. Designing a modern day bullbar means making it strong enough to take a winch or animal strike but not too strong to make your air bags go off when you hit skippy. They are actually designed to crumple during a vehicle impact. If your car does not have airbags, then you can make them as strong as you like (not smart for safetly, but you can)
I know this as i've gone through the compliance testing once already with a previous bullbar design that passed, and have another 2 bars going through in September.
