Yes, yes, and - given the relative speeds involved - no.
A 3m blindspot around a vehicle is irrelevant when it's travelling at nearly 40mph. By that point any collision is completely unavoidable. Even at 20mph 3m is only ~1/3 of a second. If a someone or something hasn't been detected before then, it's still probably too late to do anything about it.
Yet, early statements said there was no braking. They probably mean, given lack of skid marks or whatever, but the data logger should show if there was ANY braking, even if it was just prior to impact. No braking attempt = sensors not doing their job.
