I'm a little stuck... Click here to teach me more about this clue!

'arriving in this?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'greeting yorkshire racecourse' is the wordplay.
I cannot quite understand how this works, but
'greeting' could be 'hi' (hi is a kind of greeting) and 'hi' is located in the answer.
'racecourse' could be 'redcar' (I've seen this before) and 'redcar' is found within the answer.
No letters remain.
This explanation may well be incorrect...
