Formula Regional driver van 't Hoff was killed on Saturday on the final lap of the race after spinning on the Kemmel straight in heavy rain and being hit by a following car as he was unsighted due to severe spray.
The incident drew parallels to Anthoine Hubert's fatal accident at the 2019 F2 round, which occurred in the dry but also involved a driver being unable to react to a stationary car in front, on the exit of Raidillon ahead of where van 't Hoff's accident happened.
It also puts the much-maligned 2021 Belgian Grand Prix in perspective after it was halted after three safety car laps in the rain due to the atrocious conditions.
According to Lando Norris, that lack of visibility due to spray is one of the main safety problem the sport must solve.
"Between so many things that are done for safety, I think this is one of the next biggest topics, I would say, that needs to be changed," Norris said.
