When new drivers enter Formula 1, they are usually the ones on the grid with the least pressure upon them.
There are some notable exceptions. Mick Schumacher, for example, had the weight of his surname on his shoulders as everyone expected him to show his father's talent. But generally a driver's rookie season is one for them to get used to the sport, with any extra successes beyond that prime directive seen as a bonus.
Given what has happened over the course of the last month, Oscar Piastri might have more pressure on his shoulders than any rookie in F1 history when he takes to the track with McLaren for the first time next March.
