The driver responded by getting out of the car and punching him in the face, PIX 11 reported.
An anonymous 17-year-old witness told the station that he helped the SUV's driver prop Szabo upright before the ambulance came, so that he would stop choking on his own blood. But before the paramedics showed up, the driver had fled the scene.
Police released surveillance footage on Monday that they say shows the assailant and his car. The suspect has been described as a bald, dark-skinned male in a light-coloured button-down shirt and jeans.
On Tuesday, CBS 12 reported that Szabo had died. His employer, What If Media Group, confirmed the news on Wednesday morning.
"Sandor was a well-known and well-respected leader in the digital marketing industry," the company wrote in a Facebook post. "He lived in Boca Raton with his brother, but spent a lot of time in our Fort Lee, N.J. office. He was critical in helping our company's recent rapid growth, and was very proud that we were selected as one of the fastest growing companies on the Inc 5000."
Szabo was "always upbeat, positive, kind and caring," and had loved fishing and cooking, the post said.
It is with a very heavy heart that we announce that after a senseless assault over the weekend in NYC, our dear friend...

"I hope they find him and bring him to justice," Josh Gillon, What If Holdings' CEO, told CBS12. "This was really a stupid, stupid act."
According to Szabo's LinkedIn profile, he received a bachelor's degree from DeVry University in Raleigh, N.C., in 2009 and had held a variety of sales and marketing jobs in Florida and North Carolina before being hired as the vice president of sales for What If Media Group. He also listed volunteer positions with Forgotten Soldiers Outreach, a Florida group that sends care packages to military service members, and the Making Magic Alliance, a North Carolina-based organization that provided summer camp scholarships to underprivileged children.
His family has yet to comment publicly on his death, but his brother told the Daily News on Monday that Szabo was "the most loving and kind individual anyone could have as a friend."
With crime at a record low in New York City, the seemingly random act of violence shocked some residents of Long Island City, which is usually associated with glassy apartment towers and rapid development. The real estate website StreetEasy describes the neighbourhood as "sterile" and "corporate," a haven for young professionals seeking luxury housing.
"Never in a million years thought that would've happened, especially over here," James Hall, a neighbourhood resident, told CBS12.
The NYPD's 108th Precinct, which covers Long Island City, reported zero murders last year — a significant drop from 1990, when 16 people were killed. But not everyone feels secure.
"Our road is basically new hotel, new hotel, then abandoned places, so it's just a process of gentrification and converting," Cloe Lui, who lives in the area, said to CBS New York. "It'll take some time to be more safe."
