Regarding BRS. Isn"t it just like all the other "safety systems" in vehicles these days, whether they be airborne or not. Between driver and passenger airbags, seatbelts, abs, ebs, stability control, collision avoidance systems. If you have the right training and have your mind on the job, you "should" never need these things. However, if the unforseen, unavoidable, or "some other idiot" causes an incident, you might just be in a situation where it comes in handy!
