The correct spelling of the phrase "wert driver seat" is actually "driver's seat." The 'wert' is likely a typographical error or a misunderstanding of the sound of the word when spoken. In IPA phonetic transcription, the correct pronunciation is /ˈdraɪvərz siːt/. The apostrophe 's' is used to indicate possession indicating that the seat belongs to the driver. So, one should always use the correct spelling to convey the right meaning while avoiding confusion.
