COPV at least those made by Tesla are apparently radically better and lighter as has been said before. Its not like they have to hold on to hydrogen. But when controlled by a autonomous system they could be used not only to avoid accidents in a pinch but also to potentially mitigate accidents. Of course they are loud- hence emergency only. But in addition to periphery air bag type inflation (if it made sense given the forces involved) it might be possible to use the blast of air to mitigate rear end collisions by moving the vehicle in front forward while slowing the vehicle approaching from the rear with cushion of thrust. Same for side impacts. Something like this has been used in military tank active armor for a while- tank will project a tile at incoming projectile. Sometimes it could use blasts from both sides to help. And of course when its necessary to exceed the limits of tire grip to avoid impact. Guessing autonomy will drive tighter tolerances on close shave situations and this could be very useful. For instance with cars about to side bump where steering based evasive options fall short or aren't available then one or both vehicles blast air even on both sides to steady and avoid contact in a kind precision dampening. Even if there is impact its reduced and is potentially less destabilizing. So using air cushions as shock absorbents. If you've ever done sky diving over a big prop blade you know this can push you up but if you go vertical and decrease your profile you can fall into the blast even as you're slowed bit, but cars will often be presenting blunt surfaces which helps- but not always- even then smart autonomy could aim a blast if it calculated a safe steering change would increase the jet's effectiveness. If both cars, for instance, are in a cut in rear ending situation then it seems to help in every way as it pushes (if possible) the front car forward from both sets of jets (from both cars) while decelerating the rear car) solidly complementing other safety systems already built into the car. Think about black ice- this is about the only tech that is truly helpful-well maybe that and tank turn under super human autonomy control. What we are seeing here as with autonomy already 10x better than human and taking drunk drivers off the road and killing auto insurance (which helps socialize endless fossil fuel losses) we're seeing a level safety tech that may virtually eliminate traffic accidents. Hydrogen vehicles could vent their compressed hydrogen- nope its flammable but Tesla is compressed air- plus hydrogen sucks anyway. Seems like a natural addition to the Cybertruck because CT already has a compressor! Tesla is rebuilding the transport industry from the ground up from manufacturing to safety to autonomy to fuel sources. Its like we went from the Mode T to the Tesla
