[A] 三軸短車

在歐洲經常見到, 拖架空載時收起一組車輪減少損耗.
這回在維也納發現有三軸的小巴士, 大惑不解為什麼如此小車竟然要3組輪支撐...

有請高人解答

Just a guess...to maximze the interior of the mini-bus by reducing the space occupied by double rear  wheels.  As from the photo both the rear axles are single wheels instead of one rear axle with double wheels.

Please correct me if I am wrong!
