Russell took Grosjean's position as director alongside Sebastian Vettel and chairman Alexander Wurz when the Frenchman switched to the IndyCar Series over winter.
Speaking to the Beyond the Grid podcast, Grosjean revealed he still has discussions over safety with the group despite no longer holding membership since his move stateside.
“It’s good to have George managing with Sebastian in the GPDA,” said Grosjean.
“I’m still in contact with them, still part of it as a non-member [to discuss] safety issues, a few things.
"We have a WhatsApp group so I’m still in there, still giving my feedback also from my outside window. I can watch it from the outside and you see things slightly differently, which is a good asset to have.
“I think George was the right guy. We needed a youngster to be on board, to bring in new ideas, a new vision. Between Sebastian and George is, what, 10 or 15 years’ difference, which on track is not much but in life it’s a bit.”
Commenting on F1's ongoing track limits debate, Grosjean added: “Put some gravel or some grass outside of the track and then we won’t worry about track limits!”
“That’s something I really like about the US. That’s not a question that you ask yourself, and I feel like there’s been a bit too much talk about [track limits].”
