Flex you tiefing meh ideas man.
Here's what, build a massive parking complex opposite Grand Bazaar and put up a toll booth. If you park in the in the complex, you get a free bus ride into POS, if not pay your toll. Do the same on the west side.
Now put a trolley or something similar in the city where people could hop ah ride around free.
Place parking meters all over the city.
This in an effort to reduce traffic in the city.
