You can sign on as a Volunteer Special Constable (VSC)... which
is actually a part time policeman. You can then request to be
posted to TP. If you get posted there, you will function just like
any other traffic policeman.
The pay is $2.80 per hour, and you are required to work a minimum
of 16 hours each month. Of course before you can even qualify as a
VSC, you have to undergo a 9 month training course, conducted twice
a week, in the evenings.
As a VSC, i don't think you'll be allowed to drive the WRX though.

Take the bikes lah.
