Mercedes team principal Toto Wolff voiced his frustration with what he termed "Teletubbies engineers" following incidents involving backmarkers at the Hungarian Grand Prix. The race saw Oscar Piastri criticize the lapped drivers, labeling their actions as "unacceptable" after a collision with Carlos Sainz.

During the latter half of the race, leaders struggled to navigate through lapped cars due to a malfunctioning blue flag system. Normally, drivers receive a blue signal on their dashboards indicating when they should yield to leaders, but this system failed, leaving physical blue flags as the only notice.

Key moments included:

• Oscar Piastri nearly colliding with Sainz at Turn 2, leading to Piastri's eventual retirement due to a gearbox failure while running second.
• Piastri expressed his disbelief over being crashed into by a lapped car, stating, "Getting crashed into by a lapped car is never one of the things you expect."
• Carlos Sainz, penalized with a five-second time penalty, defended himself, saying he was unaware he was about to be lapped and was focused on his battle with Fernando Alonso.

Wolff highlighted the impact of the backmarkers on the podium fight involving Kimi Antonelli and Lewis Hamilton, criticizing the engineers for not adequately informing their drivers. He stated, "It's disgraceful from some of the Teletubbies engineers."

Piastri and Sainz exchanged barbs post-race, with Piastri suggesting Sainz should reflect on his actions. While McLaren team principal Andrea Stella acknowledged the incident cost Piastri time, he maintained that Sainz is generally a fair driver. The situation raises concerns about the effectiveness of communication and systems in Formula 1.
