ARP to a gateway you first must broadcast and then you can unicast ARP to the gateway but when its time to unicast ARP the interface remembers the last MAC for 3 seconds and can forward packets on without needing to wait for the ARP reply and if a unicast ARP fails the interface waits for 100ms before retrying and should that fail ARP goes to broadcast.

Not sure if something like this has already been done.
