The gesture is so mechanical few people even notice it.
As you might imagine, there are a lot of cynics on Twitter enjoying the "woman closes own vehicle door" spectacle and weighing in with their own amusing takes.
But Meghan isn't the only royal who's closed her own door before - as many pointed out on Twitter, her sister-in-law, Kate Middleton, has actually done it on several occasions.
"Yay Meghan! She's a real, regular princess/person", one wrote.
Meghan's every smile, step and wave has been scrutinised by royalty watchers curious to see how the mixed-race American actress will perform in her new role.

In fairness to MSNBC, a story about the job status of the deputy attorney general lacks an obvious visual display. Some of Trump's fiercest congressional allies had already floated trying to impeach the deputy attorney general.
Meghan doesn't just close vehicle doors with her own hands - she waves with them, too!
Comparing her accent to Madonna's, a user wrote, "Meghan's developed a case of Madonna's Accent Change #QueenOfTheWorld".
He said: "Usually royalty and dignitaries have someone to open/close auto doors for security reasons: nothing to do with "princess behaviour".
Meghan is also not concerned about her father's health due to the source claiming that, "Her mum would be the first to know if there was some serious health issue with her dad, and she would tell Meghan". Markle took in a museum exhibit at London's Royal Academy of Arts.
Again, we're talking about a simple gesture of shutting a auto door, but you don't mess with Royal protocol.
Others however, were utterly stunned that Meghan closing a vehicle door was making news.
