>We either need the enhanced cones or we don't, but only a fraction of cones being enhanced means they aren't actually that useful or that the situations without them are inherently more dangerous. Are we OK with a situation where autonomous vehicles identify the enhanced cones 90% of the time but the non-enhanced 50%? No, we want both to be very high.

I agree that we should strive to improve the vehicles' ability to detect even unenhanced cones. Doesn't mean that we can't also aim to gradually improve detection accuracy further with enhanced cones. That is, if autonomous vehicles identify regular cones correctly 98% of the time, but enhanced cones can be identified 99.99% of the time, we should be okay with a gradual transition to the latter, even though tautologically it means that the former is less safe.

We already do this with all sorts of things, safety standards improvements often have at least a grace period during which the comparatively less safe things are still allowed to exist and operate alongside the safer ones.
