Mysterious Apple Van Captured on Video in Palo Alto Residential Neighborhood
It has been increasingly speculated that these fifth-generation Dodge Caravans, which are reportedly leased to Apple, are part of the company's work on an electric car, but it is also possible that the vans are being used for a project similar to Google's Street View. It is conceivable that the rooftop cameras are being used to either collect mapping data for Apple Maps or as sensors to assist with self-driving initiatives.
Earlier this week, the Financial Times reported that Apple is hiring automotive experts to work in a top-secret research lab located near the company's headquarters. The Wall Street Journal soon followed up with a report claiming that Apple has hundreds of employees working on developing an electric vehicle, and Reuters added that the project will involve self-driving cars.
Apple is likely in the early stages of research and development for any electric car project, and it is fully possible that the iPhone maker scraps the initiative before it ever reaches the public. With both Google and Tesla already invested in electric and self-driving vehicles, it will be interesting to see if Apple enters the industry or remains on the sidelines in the months and years ahead.
