Uber Technologies Inc. has held talks with Fiat Chrysler Automobiles NV about a potential partnership involving self-driving car technology, people familiar with the matter said. The discussions are at a preliminary stage and may not result in a partnership, the people cautioned. Fiat Chrysler is one of several auto makers with whom Uber has held such talks in recent weeks, one of the people said. The growing role of technology in transportation is fueling a frenzy of global alliances between the world’s largest auto makers and the biggest tech companies. Uber is seeking new partners after some of its largest rivals forged their own alliances, including Apple Inc.’s $1 billion investment in Chinese ride-hailing startup Didi Chuxing last month and General Motors Co.’s $500 million backing of Lyft Inc. earlier this year. Fiat Chrysler, viewed as a laggard in rapidly advancing driverless technology, is in talks with several tech companies to bolster those efforts. The car maker has also held early discussions with Amazon.com Inc. about using Fiat’s cars for self-driving deliveries of packages, one of the people said. More and more companies work on self-driving car technology. Will such vehicles be popular among buyers?
