Peter was an Arena War driver and the former owner of the Arena Workshop, with the new owner now being the Online Protagonist. Bryony nervously says that he came to an unfortunate end. Before the protagonist becomes the new owner of the workshop, the player can see Peter's career path in the office, implying that Peter died during an Arena War match, and had nearly reached sponsorship level 4. He died sometime in 2018, before the events of the Arena War update.
The Protagonist gets his former Arena racing suit (spattered with bloodstains that quite likely belonged to Peter) and the player can see that Peter's name is still there.
