Trivia: The plot was reportedly inspired by a real Craigslist ad, one of the producers saw online. They brought it to Jennifer Lawrence, who fell in love with the concept and joined the production as both star and producer.
Trivia: Jennifer Lawrence has stated that everyone in her professional and personal life kept asking her over and over if she really wanted to do the scripted nude fight scene, which she could have vetoed as a producer. However, she thought the idea of getting angry and beating up a bunch of drunk teenagers after skinny-dipping was absolutely hilarious, and had to keep reassuring everyone that she had no problems with it.
Trivia: When the film was released, a big deal was made about the fact there's a 10+ year age gap between stars Jennifer Lawrence and Andrew Barth Feldman, with many expressing that they felt it was inappropriate that Lawrence was older. However, the cast and crew pointed out this as being immensely hypocritical, as Bradley Cooper is 15 years older than Lawrence and played her love-interest in "Silver Linings Playbook," which nobody complained about despite her only being only 22 at the time.
Answer: Uber has multiple rules regarding the cars drivers are allowed to use, and the van wouldn't meet most of them. Ex. It's not technically her car, so her name wouldn't likely be on the insurance policy, which is one of the requirements. It doesn't have a proper passenger seatbelt. The condition of the van itself doesn't seem to line up with what they want in terms of cosmetics and accessibility. Etc. You can't just drive any old car you want with Uber. If she tried to, she'd probably just immediately get reported by a rider, given the van's condition.
