Why are the rear doors in the articulated bus automatic doors?
On the articulated bus, I see a button with a hand on the outside of the rear doors in the trailer. On the inside, there is also a button on these doors that says "Open Door". If I press this button from the outside or inside, the doors open automatically. After about 10 seconds, the doors close automatically. The articulated buses near me have four doors. But the bus driver only has two red buttons for the front doors. Why are the rear doors on an articulated bus automatic? Why doesn't the bus driver open and close these doors? The normal buses near me (solo buses) have three doors, all of which can be opened and closed by the bus driver. Why is that like this on an articulated bus?

Ah. Because the articulated bus is so long that the rear doors are not visible in the mirror
In a curve, the rear is not visible to the driver, at least on one side.
Because a joint bus is usually about 18 meters long. And the bus driver can not look so far back in the mirror, let alone when the bus is in a curve. This is different depending on the bus.
