The correct way to spell "wast the driver seat" is actually "was in the driver's seat". The IPA phonetic transcription for this phrase is /wɑz ɪn ðə ˈdraɪvərz sit/. This spelling error likely occurred due to the lack of knowledge about the proper usage of apostrophes and the correct spelling of the word "driver's". It is important to pay attention to these details in order to ensure clear and accurate communication in written and spoken language.
