Right, it's not about the conditions, it's about the ability to perceive those conditions. However this asserts that we won't change how we construct, manage and maintain the routes of travel. Is it unlikely roads will become retrofitted in an effort to enhance the needs of autonomous vehicles?

Seems likely to me; we built EV's before we built the infrastructure to support them and conversely we created in infrastructure for petroleum vehicles before they entered mass production at the largest of scale in the period (1950's) after the fact.

I don't see how autonomous vehicles are not going to become a reality. Perhaps not in my lifetime, but, absolutely likely and possible.
