Let's not forget that Waymo requires an extensive, custom mapping and software/pre-training development process for every new city they operate in, are only in 10 cities total after over 20 years, and are still nowhere near profitability (or even with a clear plan to get there as far as I can tell).

I personally believe widely available self-driving cars which don't operate at a loss will continue to elude us until we accept the tradeoffs of dedicated lanes, a standardized vehicle-to-vehicle communication protocol, and roadside sensors. We were lied to.
