The women reported the driver to New York City's Human Rights Commission, as well as to Uber, the Daily Mail said.
"We live in this bubble and think this can't happen here in New York City".
A video one of the women took of the incident shows the driver claiming that the kiss was "illegal" and telling them to get out of his auto.
A cellphone video taken by Pichl shows the driver saying that kissing in an Uber is illegal.
At first she thought the driver was "kidding", a point that her girlfriend, Alex Iovine, 26, reiterated to the press.
The women and the driver haven't responded to messages left on Tuesday seeking comment.
"This is an open society and Uber is a platform that is available to anybody regardless of your background, your orientation, and that is sacred to us".
"It's disrespectful", the 35-year-old says.
"This blatantly discriminatory behavior described by the complainant is repugnant, and will not be tolerated in the City of New York", Fromberg said.
The Taxi and Limousine Commission is investigating. As a reminder, Uber has a no sex rule. "This doesn't feel right", Iovine said.
On the other hand, the driver is reportedly claiming that the problem was not just with the kiss, but that they were playing loud videos on the phone.
But Iovine said that was not true.
Iovine and Pichl were refunded the $22 for the ride, they told ABC News, but they are now apprehensive about using the ride-hailing service. "He was very angry".
Iovine and Pichl had ordered an Uber to ferry them from a friend's birthday party in Brooklyn to another party in East Village at around 5pm.
Iovine said she's aware of Uber's code of conduct, but was adamant that the two did nothing more than a quick smooch. "It was kind of a scary experience".
"Uber does not tolerate any form of discrimination, and we have reached out to the rider regarding her experience", Uber spokeswoman Susan Hendrick told the Daily News. It said it is investigating.
Iovine refuted El Boutari's recollection of the incident, telling the Daily News that "we would never disrespect someone else's vehicle in such manner and we always handle ourselves appropriately in public".
Both Iovine and the driver submitted complaints about the incident to Uber.
