It isn't a good idea to ignore the tram validator if interchanging either -
if heading onto the tram with PAYG you'll end up with an uncompleted tube/NR
journey depending on origin, and could be caught on the tram without a touch
in.

Yes, but...

If coming the other way, you'll be in the paid area without touching
in, so will register an unstarted journey when (if) you eventually touch
out.

You'll have touched in before getting on the tram... The touch out
follows where you eventually leave the system. Validating at
Wimbledon on the platform after leaving the tram would mean you pay
another tram fare wouldn't it? I'm *sure* this is what happened to me
once when I misunderstood the rules. (In fact, I think I paid three
times but that's another story...)
