Generally, before an F1 event, drivers enter the track on a flatbed truck, where they drive slowly waving at fans. On Sunday, before the 2025 Miami Grand Prix, the entrance was a bit flashier.
Part of the challenge in making a Lego F1 is F1 teams are typically very secretive about how their cars are made, as they try to find competitive advantages. However, Lego says teams were open to working with it for this project, ensuring that even small details on the cars were accurate. The team also worked with parts manufacturers to ensure the cars would accelerate and brake sufficiently.
F1 had shown off the cars in the weeks before the Miami race, but kept the fact that they were drivable a secret until Sunday.
