Influencers Raquel and Miguel, from Portugal, posted the daring shot to their 200,000 followers on the social media site — and fans are calling the act “irresponsible.”
The bloggers took the controversial shot while on a train that was traveling through the small town of Ella.
Boyfriend Miguel can be seen kissing the forehead of Raquel as she leans her entire body out of the train and holds on by clutching the carriage’s rails.
In another shot, Raquel is captured securing herself with just one hand, with the other one holding onto Miguel as he takes the shot.
The couple have claimed the train was “moving super slow” and said they “respect everyone’s opinions, but it’s not risky.”
But despite their claims that the train was going slow, the photo was taken when they were traveling on a bridge, and one slip could have resulted in Raquel falling down a huge ravine.
Numerous fans have commented on the photo, which has racked up nearly 40,000 likes.
One said: “You’d risk your life just for a picture? Just so you can upload it on social media? Or do you do this because this give you ‘the rush’? How is this sensible?”
Another added: “Insanely stupid stunt. You two will end up dead if you keep this clout chasing up.”
One slammed: “This will inspire more emulators to do this. Dangerous. Irresponsible and all in the name of vanity.”
Some people even criticized Miguel for putting his girlfriend in danger and not being the one fully outside the train.
However, Raquel said on Instagram: “The guy didn’t put me in danger, I’m pretty independent and I do what I feel comfortable with.”
The bloggers later added: “The train was almost not moving.”
A sobering study published in the Journal of Family Medicine and Primary Care last year found that some 259 people worldwide have died while taking selfies since 2011.
The most common ways that people die while taking selfies is by drowning, being hit by traffic or falling, according to the report.
