Interlagos Takes Unusual Step to Prevent Repeat Sprint Crashes

Interlagos organizers have implemented an unusual solution to prevent a repeat of Saturday's sprint race crashes: cutting a makeshift drainage channel into the Turn 3 kerbs. This move comes after standing water on the kerbs triggered multiple incidents, including spins from Oscar Piastri, Nico Hulkenberg, and Franco Colapinto.

Why it matters:

The safety of drivers and the integrity of racing conditions are paramount in Formula 1. The swift, albeit crude, intervention by Interlagos management highlights a proactive approach to address immediate safety concerns raised by unexpected track conditions. This rapid response aims to prevent further incidents, especially with unpredictable weather a constant threat in Brazil.

The Details:

• Makeshift Drainage: A concrete floor saw was used to cut a drainage channel along the entire length of the stepped kerb at Turn 3. This channel diverts water onto the grass area behind the kerb.
• Incident Trigger: During Saturday's sprint, heavy rain led to water pooling in the Turn 3 kerbs. Lando Norris's McLaren first threw up trapped water when he ran wide, setting off a chain reaction.
• Multiple Crashes: Shortly after Norris, Oscar Piastri lost control on the wet kerb, spinning into the barriers. Moments later, Nico Hulkenberg and Franco Colapinto also crashed at the same spot, leading to a red flag.
• Kerb Design Flaw: The design of the Turn 3 kerbs appeared to allow water to collect more than ideal, exacerbated by new grooves at Turn 2 that channeled rain directly towards Turn 3.
• Driver Reactions: Piastri admitted he "probably shouldn't have been on the kerb anyway" but noted the track's condition had changed rapidly. Colapinto described a "snowball effect" where water kicked up by leading cars made conditions worse for those behind.

What's Next:

While Sunday's forecast is dry, the organizers' decision to implement this solution demonstrates their commitment to driver safety and ensuring optimal track conditions regardless of the weather. This quick fix, though unusual, should mitigate any potential risks should unexpected rain occur during the main Grand Prix. This proactive measure ensures that a potentially critical flaw is addressed, allowing for fair and safe competition.
