The SAE levels don't really have exceptions like that: https://www.sae.org/blog/sae-j3016-update https://www.sae.org/blog/sae-j3016-update Some other quotes from wikipedia: "Level 5 ("steering wheel optional"): No human intervention is required at all. An example would be a robotic vehicle that works on all kinds of surfaces, all over the world, all year around, in all weather conditions." "Under all roadway and environmental conditions that can be managed by a human driver" I've driven in all sorts of conditions - thick fog on the highway, dangerously heavy snowfall (no lanes), fresh snow without winter tires, etc. These things are not physically impossible they just have a higher probability of killing you. So what is a reasonable definition then? A brash, foolish, broke 19 year old? A stogy, conservative 70 year old? And how do you even quantify these risks, without actually taking a ton of risks, then walking back when bad things happen? As long as there's someone out there willing to take more risks, they'll be more "capable" than an L5, thus L5s can never technically exist, since there'll always be more capable (but in actuality just plain risky) human drivers.

I understand the SAE levels, I am saying that extreme interpretations of that sentence is silly. J3016 is about a driver automation system on an otherwise normal automobile. It's not about the inherent physical capabilities of the vehicle. Level 5 doesn't require a vehicle to have studded tires to operate on ice, amphibious capabilities to operate in floods, or other extraordinary physical capabilities beyond the normal abilities of an otherwise typical underlying vehicle. We have a while before we get anywhere close to having to consider this -- but at some point we're going to have to come to terms with the fact that a significant problem with human drivers is that they often choose to operate their vehicles in conditions beyond the safe capabilities of the vehicle given particular conditions. Neither road conditions nor the laws of physics disappear at any SAE level. These things are always something that will be taken into account. There will always be some amount of risk that cannot be determined in advance. Even I do not know when the snow plow will go down my street, and that may determine whether I can fully make it home or not. I'm sure the folks at the SAE have driven in inclement conditions before, so it makes sense to interpret those definitions with a reasonable lens.
