WireGuard Gives Linux a Faster, More Secure VPN

MACs are computed directly from cryptographic hashes. For normal ZeroTier P2P traffic the MAC and Ethernet header are elided entirely too, which saves about 14 bytes of per-frame overhead.

Wait, are we talking about MAC as in cryptographic Message Authentication Code, or MAC as in ethernet Medium Access Control (addresses)?

MAC as in 48-bit Ethernet addresses.

There's a tiny chance of a collision, but for it to be meaningful you'd have to have a virtual LAN with millions of devices on it.
