Among those talents is Ollie Bearman who, despite having never competed in a full season of F1, no longer counts as a rookie according to the FIA's definition, having competed in three grands prix in 2024.
The 19-year-old has signed with Haas for 2025 but served as a reserve driver for Ferrari as well last season, stepping in for a recovering Carlos Sainz and impressing at the Saudi Arabian GP.
The British racer then covered for former Haas driver Kevin Magnussen on two occasions, with the Danish star serving a race ban in Baku and being taken ill in Sao Paulo.

As Bearman and new team-mate Oconprepare for their first season with Haas, the pair are set to take to the track in a private test alongside Ritomo Miyata in Jerez, Spain.
The trio are set to test previous Haas cars this week on January 15th and 16th, Bearman taking to the wheel of the VF-23 on Wednesday and Ocon on Thursday.
As a result of the team's partnership with Toyota, Miyata, who races for Toyota GAZOO and is set to compete in F2 in 2025 with ART, will then finish the running on both days.
