I agree with this in general, but a couple of points: 1. Suppose a vehicle operates in revenue service for 8 hours per day, 365 days per year, that's a labor cost of $44k. If the hardware lasts five years, you break even if the hardware/upkeep costs of the self driving part are less than $220k, which seems very doable. 2. I think that Alphabet's golden goose is more vulnerable than ever. Google's search results have become so ad-infested that the mere willingness to dial down the number of ads is enough. What good are great organic search results if the user never sees them because there are only one or two on the entire first page?
