The halo saved Roy Nissany's life after a collision at Silverstone on Sunday morning, and the drivers' lives saved by it since it was introduced also include the likes of Lewis Hamilton.
Drivers, fans, and team leaders lobbied against the halo cockpit head protection device during 2016 and 2017.
Toto Wolff, Mercedes' chief, has even said he would rather handle a chainsaw to it, as F1 cars are completely open-air, giving the most vulnerable and exposed part of a driver some protection at least.
IndyCar will also adopt the aeroscreen device in 2020.
On numerous occasions, the halo has saved the lives of drivers, including seven-time world champion Lewis Hamilton.
Roy Nissany was saved from an accident when Dennis Haugers' car rammed into his halo, preserving and rescuing the Israeli driver at Silverstone in 2022.
Who are the drivers whose lives have been saved by the halo in F1 and F2?
A serious collision occurred during this morning's F2 race at Silverstone, as Dennis Haugers' car was lifted up and ended up on the top of Roy Nissanys. Both drivers were unhurt due to the life-saving halo.
The halo has saved the lives of drivers.
The halo saved its first driver in the 2018 F2 race in Barcelona pretty early on in its inaugural season.
Nirei Fukuzumi and Tadasuke Makino met at Turn 4, the latter being pushed above his Japanese counterpart early in the sprint race.
Fukuzumis Arden landed on the top of Makinos Russian Time, the majority of the impact being absorbed by the halo rather than the Makinos helmet as it would have done in 2017.
The halo was only used for the fifth time in a grand prix race, and it was the second for Formula One, which had already demonstrated its value in saving the life of a racing driver.

At the start line-up in the Belgian Grand Prix later in the year 2018, the halo came to the aid of Charles Leclerc.
Nico Hulkenberg misjudged his braking timing for Turn 1 and dropped-kicked Fernando Alonso's McLaren over the pack.
Alonso landed on the top of Leclercs Sauber, with the front suspension and wheel deflected and breaking apart by the halo.
The halo saved Leclerc's life as the first Formula One driver.
The halo saved the lives of a Formula 3 driver heading to the 2019 Italian Grand Prix weekend.
Alex Peroni was launched by a sausage kerb that flipped out of control and landed upside down on the tyre barrier as he exited the Parabolica.
Peroni escaped with only broken vertebrae in his back, thanks to the vehicle landing right side up.

All doubts about Grosjean and Hamilton have been answered.
With Romain Grosjean's first lap fiery accident, any and all doubts about the halo and its ability to save the lives of drivers were put to rest in the 2020 Bahrain Grand Prix.
After contact with Danill Kvyat, the Haas driver hit the barriers, sparking a fire that splintered the vehicle in half.
Grosjean spent 28 seconds in the burning wreckage before escaping with burns to his hands.
As Grosjeans came into contact with the barrier, it showed evidence of being pushed up by the halo.
This would have been a Grosjeans helmet that hit the armco barrier in the days before halo. This would have resulted in non-survivable head trauma.
The third and final F1 driver to be saved by the halo is the most successful driver in the series' history.
Lewis Hamilton is just another driver, facing the same dangers as the others in his 103 world championship victories.
For the second time in a row, Hamilton slammed with championship competitor Max Verstappen at the 2021 Italian Grand Prix.
Hamilton sought to squeeze, fairly, Verstappen, attempting to climb the inside into an ever-closed wedge, exiting the pit-lane.
Verstappen was launched by a sausage kerb and landed on the Mercedes.
Hamiltons halo shattered the Verstappens floor and right rear suspension, saving the Briton from serious injury or death as he ducked down in the cockpit.
Hamilton vowed to continue in the race, but was eventually told by the team to turn it off.
