Vehicle certainly requiring good skill to corner?
I believe the answer is:
go-kart
'vehicle' is the definition.
(go-kart is a kind of vehicle)
'certainly requiring good skill to corner?' is the wordplay.
'certainly' becomes 'ok' (I've seen this in other clues).
'requiring good' becomes 'g' (I can't justify this - if you can you should give a lot more credence to this answer).
'skill' becomes 'art' (I've seen this before).
'to corner?' is an insertion indicator (corner can mean to trap).
'g'+'art'='gart'
'ok' placed within 'gart' is 'GO-KART'.
Can you help me to learn more?
(Other definitions for go-kart that I've seen before include "Small racing car" , "Small, low racer" , "Lightweight racer" , "Small motor-racing vehicle" , "Miniature racing car with skeleton body" .)
