The beauty and usefulness of OFDM is at the receiver. Those multiple subcariers allow easier DETECTION in a multipath or interference environment. Those subcarriers being transmitted can be done at a lower signal speed and are aggregated at the RECEIVER into the original high speed signal. The transmitter isn't adapting per se.
