I am not sure why the difference in energy related to vehicle mass is relevant here as humans have an insignificant amount of mass compared to either vehicle, so transferred energy should be roughly the same. However, the difference in how the collision plays out (pulled under Vs thrown above) should be a huge impact

I am not sure if this is helpful but I just created a systemd unit that sets up the network namespace in the background. Then, as I use nixos, I add the wireguard VPN to nix and with networking.wireguard.interface.name.interfaceNamespace you can then move it into the container. For running applications I cannot really comment because I have only one service making use of the VPN which runs inside a NixOS container for which the namespace can be configured with --network-namespace-path=/run/netns/…

Did you look into network namespaces? With these you should be able to dedicate a namespace for the VPN adapter and then move discord into it, at least with wireguard it works flawlessly.
