'rides here' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'you once around motorway then stops' is the wordplay.
'you once' becomes 'thee' (historical second person pronoun).
'around' is an insertion indicator.
'motorway' becomes 'M' (as in motorway names - Mp, Mk etc).
'then stops' becomes 'parks' (I can't explain this - if you can you should give a lot more credence to this answer).
'thee' enclosing 'm' is 'theme'.
'theme'+'parks'='THEME PARKS'

'with' acts as a link.
