In addition to what @Jesstzn offered, note that this is the right button on the R-side 4-way rocker and that the icon on the instrument cluster changes to show this change. You can also long-press this right button on the four way to change to regular cruise and back to ACC/LSF. See pages 416-429 in the OM.
1) Honda has never been a leader in bringing computing technologies to their cars. 2) They wouldn't do it in the low-price car first, maybe in an NSX. 3) They wouldn't do it in an existing model--it would only make sense introducing it in a new ground-up model. 4) They haven't even figured out how to sell/support infotainment system software yet. Be careful what you wish for.
