In these people may drink and drive (7)
I believe the answer is:
saloons
'drink and drive' is the definition.
I can't tell whether this defines the answer.
'in these people' is the wordplay.
I cannot really understand how this works, but
'people' could be 'loons' (loon is a kind of person) and 'loons' is present in the answer.
The remaining letters 'sa' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'may' is the link.
Can you help me to learn more?
(Another definition for saloons that I've seen is " Bars".)
