Two Saudi women detained since early December for challenging the conservative kingdom’s ban on female drivers announced on Thursday that they had been released after 73 days. 
  
 Loujain al-Hathloul and Maysaa al-Amoudi, who both have valid driver’s licenses from the United Arab Emirates, posted messages on social networks after news of their release was reported by The Wall Street Journal. 
  
 Ms. Hathloul, who had documented her effort to drive into Saudi Arabia from the United Arab Emirates on Facebook and YouTube in late November, confirmed late Thursday to her 232,000 Twitter followers that she was free. ||||| Image caption Thousands have signed up to a campaign to defy the ban 
  
 Women who drive risk damaging their ovaries and producing children with clinical problems, according to a conservative Saudi cleric. 
  
 The comment, made by Sheikh Saleh al-Lohaidan, came as activists step up their campaign for women in Saudi Arabia to be allowed to drive. 
  
 Women are being called upon to defy the ban and drive on 26 October. 
  
 The campaign, started on Twitter, has attracted more than 11,000 signatures. 
  
 It is the latest in a series of campaigns over the past two decades for women to be allowed to sit behind the wheel. 
  
 Women activists in Saudi Arabia say the issue of being allowed to drive is key to gaining other rights Saudi women seek right to drive 
  
 The ban on women drivers, while informal, is enforced by Saudi police through fines and arrests. Only men are permitted to acquire driving licences. 
  
 "If a woman drives a car, not out of pure necessity, that could have negative physiological impacts as functional and physiological medical studies show that it automatically affects the ovaries and pushes the pelvis upwards," Sheikh Lohaidan told the news website Sabq.org. 
  
 "That is why we find those who regularly drive have children with clinical problems of varying degrees." 
  
 Sheikh Lohaidan is reported to be opposed to reform more generally and granting women more rights in the kingdom. 
  
 Opponents of giving women the right to drive in Saudi Arabia say it offends the country's traditional code. 
  
 But those behind the campaign for the ban to be lifted point to inconsistencies, such as the need for women to employ a male driver who is not a family member. ||||| Uber 
  
 San Francisco-based Uber — a smartphone app that connects passengers with cars for hire — officially launches in the Saudi capital Riyadh today after three months of beta testing, entering a new market with some unique opportunities. 
  
 Saudi Arabia is a country with virtually no public transport and where half of the population — women — is not allowed to drive. Many of the regular cabs available in big cities are in poor conditions, with broken meters and foreign drivers who cannot read street signs written in Arabic.

 Karim Khattar, Uber’s general manager in the country, says the testing period in Riyadh has been better than expected. A few weeks ago they also started testing the service in the coastal city of Jeddah. 
  
 Uber, which was founded in 2009 and last August raised $258 million from Google Ventures and other investors, is not the only company to see potential here. Similar apps like Dubai-based Careem and Brazilian Easy Taxi have also begun offering their services in Saudi Arabia over the last few months. 
  
 The on-demand ride services usually work like this: After users download the free app on their smartphones, they can register for the service entering their personal information and credit card number. Once it is set up, users can see their location on a map that also shows available cars nearby with an estimated time of arrival. 
  
 The user then can tap on the screen to order a car. If the order is accepted, the person can see the car moving on the map until it arrives. After the user reaches the destination – he or she can leave the car immediately without money changing hands with the driver, as the fare of the trip will be automatically charged to the credit card. 
  
 Uber has experienced a rapid growth in recent months, and the service is now available in 100 cities around the world, up from 42 cities last September when they had their regional launch in neighboring Dubai. But the quick growth didn’t come without pain: the company faced protests by taxi drivers in cities like Paris and London, and new competitors continue to crowd the space. 
  
 But Mr. Khattar said they are not worried. “Each player has its own place in the market, he said. “There are different players and everyone finds their own niche.” ||||| "If you can't find a driver, you have to wait for your husband. If not your husband, then your brother. And you know sometimes everyone is just so busy that going from point A to point B is really difficult," she said. "You can't even walk because [often] there's no sidewalk, so you're afraid of getting hit by a car." |||||

With female driving in Saudi Arabia effectively banned, mass transit not that great, taxis unreliable and dirty, and private cars expensive, women can have a hard time getting around in the country, the Los Angeles Times reports. "If you can't find a driver, you have to wait for your husband," Hala Radwan, a 29-year-old resident, tells the paper. "If not your husband, then your brother. … Sometimes everyone is just so busy that going from point A to point B is really difficult." The increasingly popular way now for ladies to get around town? Uber, local service Careem, and a handful of other ride-sharing services, the paper notes. The app companies there say more than 80% of their single-rider users are Saudi women, per the Times, while a regional GM for Uber notes that the number of users in the kingdom has multiplied by 20 since the company ventured in last year. Technically there's no law prohibiting women from driving in the kingdom, but because of cleric-issued fatwas, women can't get driver's licenses, the Times notes. Other reasons conservatives spout for not letting women get behind the wheel in the gender-segregated state range from their ovaries getting damaged to increased chance of rape if their cars break down to coming into contact with male medical staff after car accidents. So ride-sharing it is, for now, for working women stuck in the system. That includes Radwan, who coughs up $700 or so a month to Careem to get back and forth to her marketing job. She says the GPS technology in Careem's cars makes them safer than taxis, and no one can tell she's not in a private vehicle—important since women using public transportation solo in Saudi Arabia are also seen as "lacking morals," the Times notes.
