The Spin

Narrative A

F1's new cooling vests are a smart safety innovation that's rapidly improving. Teams are continually improving the systems, extending their effectiveness from 30 minutes to over an hour. Drivers like Sainz remain confident that they can handle Singapore without the technology if needed, but it offers clear benefits with minimal risk.

The Race

Narrative B

The cooling vests are an uncomfortable, unreliable technology that drivers don't want to use. Multiple drivers report itching, discomfort and bulky designs that interfere with their racing. The systems can fail or exacerbate the situation by circulating hot water, creating dangerous situations, especially during intense heat waves.
