🚗 台 = stand/platform: one dai per machine sitting on its base
台 means a stand or platform. Heavy things that rest on a base (cars, TVs, computers, washing machines) are counted with it. Sound hook: dai is like a die-cast toy car, so count cars as ichi-dai, ni-dai, san-dai.
台 — mouth 口 + 厶 (private)
Originally depicted a raised platform or terrace, suggesting elevation and a place to stand. The character later extended to mean stage, podium, or station. In modern usage it also serves as the simplified form of 臺 (platform) and 颱 (typhoon), and names Taiwan (台灣).
