A couple of ex-riders are of the opinion that disc brakes don’t help in situations like this - riders grab a handful of brake and go over the bars.
The film might seem to bear this out.
You can grab a handful and go over the bars just as easily with rim brakes. I'm generally pretty good st modulating my disc braking- e.g the pedestrian who stepped out into the cycle lane from in front of a bus in the traffic lane - I stopped right at her feet, but now vertically positioned above my front wheel.
Sometimes a crash is inevitable.
