Sep.1 - The FIA is investigating the way in which George Russell's car struck a flying wheel at high speed during the Belgian GP.
"It was bad luck that I hit it, but it could easily have hit a marshal or someone in the crowd, if there had been a crowd," Williams' Russell told RTL.
"You learn from every accident and we clearly have to make improvements here."
However, strict regulations already exist that tie the wheels to the chassis with Kevlar tethers in the event of heavy crashes.
F1 race director Michael Masi admits the way Giovinazzi's came loose is a "concern".
"I can't say with 100 percent certainty what went wrong. It's too early to draw conclusions so soon after an incident like that," he said.
"We will look at all the data very carefully," Masi added.
