It might require moving to the Tesla camera-only approach to bring down costs enough to make self-driving cars viable. But that technology is still nowhere near there.
High-precision accelerometers used to be extremely expensive, with the best having prices in the high 5 figures. Then companies started putting (initially really crappy) accelerometers into smartphones, just to know which side is up. Then economies of scale hit and suddenly every smartphone has an accelerometer better than those super-expensive ones, and cost per part is pennies. (And then drones became a thing.)
The same will happen with LIDAR. Nothing about any of the parts of a self-driving car requires it to be super expensive, it's just that things that are made in quantity are cheaper than special snowflake parts.
Also, if we assume the cost of a self-driving car is 250K, that might seem like a lot, but if you amortize it over 5 years, that's 50K a year. Assuming that a car can bring in a mean profit of $10 per ride, that means it has to do 13.7 rides a day for 5 years to break even. That might seem high, but these cars are not human drivers, they don't need to sleep or take breaks, they could be on the road 20-23 hours a day, leaving some time for refueling and maintenance. I think it would be possible to bring in a profit with $250K self-driving cars and an uber-equivalent price points. It will become even easier when these cars drop to 200K, 150K and 100K, which is certain to happen once the technology spreads.
It’s brand suicide to not have a car when needed so fleets will be sized for peak load. When you apply queuing theory none of the numbers seem to add up.
If an advertiser tried to entice people to place a tracking device in their cars today for a reward, that would go over like a lead balloon. But Waymo will get people to pay for the tracking data and enjoy the riding convenience, while vacuuming up insights into consumer behavior at granularities that are the story elements of Black Mirror episodes. Advertisers are salivating at sending targeted offers that add pinpoint location and time to the axes they can already select upon.
