This is sometimes true, as CSMA/CD+ACK may also involve collision detection and retransmission of packets if a collision occurs during transmission. Additionally, if a wireless NIC receives an ACK for a transmitted packet, it knows that the packet was successfully received by the recipient and may proceed with transmitting the next packet immediately without having to wait for traffic to stop.
