There are already limitations by road condition. This level of control over the operating environment is part of why so many services are targeting robotaxis as their initial product.
Would a robotaxi in Detroit, Chicago, or Minneapolis in the winter be viable? I'm thinking about those roads where it's nominally a two lane in each direction, but the snow banks make it a 1.5 lane in each direction (if that). Where one doesn't start into the intersection when the light turns green - to give any cars that have the need to slide through. And likewise the ability for the robotaxi to realize "well, I've…
Before launching in any city, you have to validate that you can handle the idiosyncrasies of its driving environment. Perhaps the business side decides that Detroit isn't worth launching in, but is drivable 200 days/yr and that's enough to warrant launching an intermittently-available service.
My ultimate point is that AVs can cover a lot of ground from a business perspective without getting to full universal-availability. This is helped along by a combination of validating each city independently[1], limiting operating conditions, and safe-fallback teleoperation for occasional use.
Validating a 2021 AV in a snowy environment isn't an inherently harder problem than validating a 2016 AV in a normal environment (with a safety driver), and a similar approach will be applicable.
