Wanna share some experience of mine yesterday when cycle kesas.

As usual, finish my route, went for a tea break near Seri Petaling.

Was blocked by JPJ....a major operation.
My car was kena beacuse of HID. No question on that.
The officer then start his conversation.
JPJ:wah pergi cycle huh..mana u cycle?
Me:kesas route.
JPJ: Owh...eh, salah tau basikal you letak dalam kereta. Passenger seat dah fold then you pulak letak basikal.
Me: Salah???Apasal Salah...basikal tak terkeluar pun
JPJ: Kalau nak bawa basikal dgn kereta...you kena apply dan pasang roof rack.
Me: Owh....kena apply lagi kat JPJ untuk kebenaran pasang roof rack tu?
JPJ: Ya.
Me: Sorry tuan...Saya tak tau la ada ini undang2. Takpe, Saya akan mohon ya.

My question is, private car cannot carry bike inside the car??
As far as i concern, as long as the object does not above the side window and rear windshield it is not wrong doing.

Is my understanding correct? Pls enlighten. Thx
