Verstappen has repeatedly voiced his concerns over F1's growing calendar, which will peak at 24 races next year and involve nearly 200,000 miles of air travel despite modest efforts to reduce its footprint.
A double-header in Bahrain and Saudi Arabia will kick off F1's record season, followed by four individual flyaway events in Australia, Japan, China and Miami as well as two triple-headers later in the year.
On top of that F1 has added up to six sprint races per season, which adds extra strain on the team personnel.

In an interview with Dutch newspaper De Telegraaf, Verstappen says F1's unrelenting thirst for growth is sometimes making him consider "whether it is all worth it" to stay involved.
"I'm worried about the sport I have always enjoyed," said Verstappen, whose 2028 Red Bull F1 deal could potentially be his last. "I still do, but only to a certain extent.
"It's not that I'm totally against change, like some people claim. But those changes have to be benefit Formula 1.
"Why do you have to change things when they're going well? I think a traditional qualifying session is a great format, it doesn't all have to revolve around money.
"People might think, 'Well, he makes a lot of money, what is that guy complaining about?' But it's about your wellbeing, how you experience things and not how much you make.
"I feel like I have to do too much and skip other things [I enjoy doing], so I sometimes think, 'Is still worth it?'"
