Be transported in a car, ideally (4)
I believe the answer is:
ride
'be transported' is the definition.
(I've seen this before)
'in a car ideally' is the wordplay.
'in' says the answer is hidden in the clue.
'RIDE' can be found hidden inside 'car ideally'.
(Other definitions for ride that I've seen before include "Fairground entertainment" , "Go by horse" , "Travel on the back of animal" , "A dire sort of journey" , "Travel by horse, bus, etc" .)
