The "two spaces" you are referring to are the wheel axles.
This design is prevalent for buses with zero step feature, like the
Volvo SBS1688M and the B9TLs...even our SMRT new WAB buses
too...the SMB1H
They take up space...I agree. But the design of the bus is
as such...
Thanks
Another idea is to follow the seating arrangement as 8030L. Soon
Chow put a seat before the left front axle, which is closer
to the BC. But that still won't help. Another way is to put
foldable 'theatre-style' seats at the standee area. Around 5 - 6
could be installed in a paralel position. Hence, the problem can be
solved. I hope SBST and SMRT sees the demand from the public.
Another costly method is to buy new buses that uses 'wheelchair
lifts' that brings people up and down the bus. These types of buses
are seen in operation in the USA. This helps increase seating
capacity abit but space for PIWs still has to be considered.
Setback is maintainance and complicated way to operate.
