"Life's more fun when you live in the moment" is Snapchat's description on the Apple App store. Mr Wentworth Maynard, who was hit by another driver speeding while using Snapchat, may disagree with this.
Mr Maynard, who had just started his shift as an Uber driver, was merging onto a four-lane highway in Atlanta, Georgia, when he was hit by Ms Christal McGee driving at 172kmh.
Snapchat, the popular social media app which allows users to document and share their lives with their followers, has a speed filter that shows how fast users are travelling.
According to CNN Money, Ms McGee was using the Snapchat speed filter when she collided with Mr Maynard's car, on Sept 10, 2015. Mr Maynard's lawyers said that 18-year-old McGee wanted to post an image of herself going fast on Snapchat.
Preoccupied with capturing the moment, she did not notice that Mr Maynard's Mitsubishi Outlander had pulled out on the road. According to his lawyers, his car was hit "so violently it shot across the left lane into the left embankment".
A passenger in Ms McGee's Mercedes c230 said that at one point, the car's speed had reached 181kmh, which greatly exceeded the 89kmh speed limit for the highway.
Mr Maynard had traumatic brain injuries and spent five weeks in intensive care. He still suffers from depression and memory loss.
He is seeking monetary compensation to pay for his medical bills and lifelong care.
One of his lawyers, Mr T. Shane Peagler, said: "We'll see to it that Christal McGee is held responsible, but we also want to see Snapchat held responsible."
Ms McGee, who had just left her shift at a restaurant at the time of the accident, was also injured.
Shortly after the collision, she posted a photo of herself on Snapchat, captioned "lucky to be alive", showing her on an ambulance stretcher with blood trickling down her head.
According to Digital Trends, a technology news website, distracted drivers cause almost one-third of car crash-related injuries in the US .
This is not the only case of drivers Snapchatting while driving.
In February this year, reality TV star Kylie Jenner took photos of her steering wheel while driving.
