Last Sunday's F1 sprint race in Barcelona saw a collision between F2 racers Tadasuke Makino and Nirei Fukuzumi.
The fact that the two drivers came together was hardly a remarkable event given the fierce battles that take place up and down the junior category field.
A spectator's picture of the contact however shed some light on just how close Makino came to suffering a severe injury when he was hit by his rival, whose pink car mounted Makino's machine, its left rear wheel only avoiding hitting the Japanese driver thanks to… the Halo.
The controversial cockpit safety device, still decried and condemned for its ungraceful aesthetics, may have saved a driver's life last Sunday. And that's pretty much all we need to know about its effectiveness and ubiquitous presence in single-seater racing and in Formula 1.
