Not that I want to get involved in this debacle but what you've posted is exactly the thought behind the "single point of release" rule. The window net is a restraint as is the recommended right-side net - the latest ruling of having the window net drop down befuddles me though - I'd rather that it fall AWAY from the vehicle (read: fall up) when the vehicle is inverted.
Having watched Puskar Motorsports at Nelson last weekend, they have an "extricator" who removes the driver from the vehicle. Aside from his belts, when the "extricator" pulls the driver, everything else WILL break away which is how those periphreals are designed. For example, F.A.S.T. specifically states that their water line connectors are break-away in case the driver needs to exit the vehicle NOW.

And the flipside is the rest of the world.
I've watched Pro drivers, guys who get in and out of cars for a living....guys who are as cool under pressure as anyone, have their heads or bodies stuck in cars after incidents, and it's happened for all the items that need releasing to get out of the car. Sure, a radio connector pops right out when pulled from the right direction... and it's easy to set it up so that it will always pull from the right direction, but lots of teams haven't set it up that way. Hence guys get their heads stuck in the car after a crash. The HANS is no different.
The one point release rule is a total joke, as evidenced by Kevins sternum strap. (Sorry Kevin). Heck, grid workers are actually complimenting him on it, even though by the strictest definition, his restraints now require TWO points of release. Huh?? Should this mandate come to pass, these will be the SAME grid workers who will take an Isaac from his car to protect him from having too many points of release, but won't say "Boo" about his sternum strap!?
The bottom line here is that the SCCA has a set of requirements that were written long before things like HNRs were around, and they've essentially closed their eyes to the release rules' hypoctrical nature.
For the SCCA, now is the time to step back and look at the big picture. Use common sense in the rules. Mandate double buckles on window nets (like mine), mandate methods of drink tube, radio harness and air tube connections. But don't keee jerk reaction HNRs situation requiring 38.1 devices, then further knee jerk it by realizing the huge weakness in lateral impact protection 38.1 devices provide by then requiring huge "wing" seats....which would make the already difficult egress issue even worse.
This is that point in time where we will look back a year from now and say, "
That's when we got in this mess".... Let's control our destiny, let's think big picture and not just react out of fear.
