Uber spent $457 million last year on research and development of autonomous vehicles, flying cars (known as eVTOLs) and other “technology programs” and will continue to invest heavily in the futuristic tech even though it expects to rely on human drivers for years to come, according to the company’s IPO prospectus filed Thursday.

R&D costs at Uber ATG, the company’s autonomous vehicle unit, its eVTOL unit Uber Elevate and other related technology represented one-third of its total R&D spend. Uber’s total R&D costs in 2018 were more than $1.5 billion.
