A sensor choice is also a decision about how much real-world data you can ever collect.
Two shops. One roasts a rare bean and sells forty cups a day. The other sells a decent cup to thousands of people. The second shop learns something the first cannot: what a huge mix of customers actually does, complains about, and repeats. Volume is information, not only revenue.
Sensor cost works like that in autonomy. An expensive suite can be justified on a research fleet of hundreds of vehicles. A cheaper suite can ship on every vehicle a maker already sells, including vehicles that never run a paid robotaxi route.
One roasts a rare bean and sells forty cups a day.
That difference compounds. A large owner-driven fleet covers many weather conditions, road types, and cities as a side effect of ordinary use. A dedicated test fleet covers a thinner slice, in the places it was staffed to operate, and every mile has an operating cost.
So the hardware decision quietly sets the size of the learning loop. Inexpensive sensors can mean a larger, messier corpus. Expensive sensors can mean richer geometry per mile and far fewer miles.
Neither choice is automatically correct. It does explain why the argument stays heated. It is not only a hardware preference. It is an argument about whether the scarce resource is precision per scene or variety across scenes.
