No need to touch off if travelling between zones 1 & 2.

As the title says, if your regular commute is between zones 1 and 2, then there is no need to touch off when you arrive home at night.

There are of course situations where it is still advantageous to touch off, but if I started explaining those, your eyes would glaze over and your brain would turn into something resembling Maccaroni and cheese.  The information of course is out there for you to find, you just need to know where to look.  In fact I may have posted about it on this very blog in the past, try looking there.
