From the way, you
wrote, I believe you should be a car owner. Allow me to say some
even given their van to drive taxi. while the rest may have given
up and take public transports.
Vans are mostly for commercial use, they are no really belonged to
some luxury groups (No mentioning that those that required car to
conduct business or work). Occasionally, maybe used for carrying
workers or passenger. (We don't expect them to have human carrier
and good carrier, rite). For businesses that required a van or
truck to operate, for big big company will be small small
problems.
However, for SME or OMO companies will be bigger issues hence by
putting them together, likely to see more peoples "walked the road"
I would not encourage this to happen.
We don't see much of peoples driving cars more than 8 hours a day
if they are office bounded high salaried officer. We do see lowly
paid serviceman, delivery man, van sales etc on the road more than
8 hours. By using, it is already a punishment, (ERP, diesel, more
maintenance, wear and tear, more chances of paying fine, accidents,
carpark payment, get heated and wet, kidney problems and many other
etc). Why wanted to make them suffers some more.
