Japan vs India Trailer Coupling Hack | This is really MASS!

Описание: Japan vs India Trailer Coupling Comparison 🔧
In this video, we show how the two countries handle trailer coupling systems completely differently at the MASS level!

🇯🇵 JAPAN : Super fast automatic coupling, high precision lock, zero manual handling.
🇮🇳 INDIA : Strong manual coupling, alignment technique, safety locking — field-tested & powerful.

Both methods have their own engineering logic.
This video is not a simple comparison — it is a MASS learning video for engineering lovers, mechanical students, transport operators.
