Computer facility in cars welcome (8)
I believe the answer is:
autosave
'computer facility' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'cars welcome' is the wordplay.
'cars' becomes 'autos' ('auto' can be a synonym of 'car').
'welcome' becomes 'ave' ('welcome' or 'farewell' - from Latin).
'autos'+'ave'='AUTOSAVE'
'in' is the link.
Can you help me to learn more?
(Another definition for autosave that I've seen is " facility for forgetful authors?".)
