Lyft has exited autonomous car space by selling its unit to Woven Planet, a Toyota subsidiary. Uber did the same thing by parting with its autonomous unit. Some startups in this area have merged with bigger companies. Still a lot more work is to be done for a number of years to make autonomous cars a reality. Several billion dollars additional funding is required. This could stretch to the end of this decade. Silicon Valley’s big tech companies have faced problems in perfecting the technology. One of the most hyped technologies, it attracted heavy investments. Still science is advancing with one better ride at a time. Google’s Waymo has already launched the world’s fully autonomous taxi service. It is by itself a major milestone.
