malaysiakini and the PROBLEMS of the NEW CIQ

After spending more than RM1bil on a new CIQ (the famous crooked bridge) project, it is a downright shame that we still read of basic problems that affect thousands of travellers who use the facility every day.
This letter in malaysiakini highlights the problem. In Traffic solutions needed for Johor's CIQ complex the writer suggests that the old complex should still be used for bus passengers and other pedestrians.
There are some advantages to this such as:
1.Perhaps 60% of passengers will disembark at the old checkpoint and walk to the town; thereby generating more revenue for the shops in the area.
2.There will be less congestion at the new CIQ.

I wonder if the authorities actually made any studies on how many actually left the buses at the old CIQ and how many walked the Causeway to/from Singapore.
The main problem with more passengers being handled at the old checkpoint is the flow of traffic and some security/safety issues.
For pedestrians, the new CIQ appears to be a traveller's nightmare.

I guess the old checkpoint will be converted into commercial space as part of the Crooked Bridge Project.
