Häkkinen was criticized for being a poor car developer, though this may have been exaggerated due to his initial struggles with the English language early in his career.<ref name="atlasf1oct1998"/> [[Adrian Newey]], the designer of Häkkinen's championship-winning McLarens, described an instance of Häkkinen's approach to input on car development when Häkkinen kept telling him during the initial testing of the [[McLaren MP4/13]] that the car was understeering. Newey subsequently adjusted the car to correct for understeer, but this only made it slower. After digging deeper into the test data and listening closely to what Häkkinen was describing Newey realized the car was not understeering but had rear end biased instability on corner entry that Mika was compensating for with understeer. This experience proved crucial for Newey's relationship with Häkkinen during their run together at McLaren, as after that Newey no longer had issues understanding Häkkinen's inputs on car development.<ref name="auto">Archived at [https://ghostarchive.org/varchive/youtube/20211211/kmb02SBmE1I Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20201105011422/https://www.youtube.com/watch?v=kmb02SBmE1I&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web |title=Engineering the Greats: Adrian Newey |url=https://www.youtube.com/watch?v=kmb02SBmE1I&t=368s |website=Youtube |publisher=Motor Sport |access-date=4 August 2020}}{{cbignore}}</ref> Newey also said Mikathat Häkkinen's countryman, protege, and future McLaren driver [[Kimi Räikkönen]] also had a similar approach to input on car development.<ref name="auto"/>
