Understand confusing feature names

Feature-name explanations

Steering while managing speed

MADS, AOL, ALKA, and UFC are not synonyms

They may serve a broad user goal, but brake, accelerator, cruise-cancel, and main-cruise behavior can differ. Stock accelerator override is not automatically MADS.

Experimental behavior

Manual Experimental is not a dynamic switcher

DEC, CEM, CCM, and AEM automatically choose modes using project-specific triggers. Their names and logic stay separate, and most require reviewed longitudinal context.
