> “The real problem is that the car is too safe...”

no. this statement is fallacious, and i believe it is dangerously misleading. it sounds like something out of the mouth of a corporate attorney, and not someone who cares about being actually safe. out here in the real world driving laws are more like guidelines.

my take on the situation is the car knows and follows all of the written rules of the road, but not the unwritten ones. kind of like a 16-year-old kid who's just aced his driving exam, but doesn't yet have a feel for driving. every so often he encounters a situation not covered by the law or the driver's handbook, and he's forced to choose the safest course of action on his own.

i live near google in mountain view, and (usually) encounter the self-driving SUVs many times a day, either biking around town or as they drive past my residence. in hundreds of encounters i've only witnessed one potentially dangerous incident (many months ago) involving a self-driving SUV. it wasn't clear to me who/what was at fault.

whilst making a protected left turn onto west el camino real from el monte ave [0], a self-driving SUV came to a complete stop in the middle of the intersection, causing the vehicles behind it to halt and lay on their horns. since the incident occurred a few yards behind me (over my left shoulder) i don't know exactly what precipitated the incident, but reflecting on the experience has caused me to recognize some potential flaws in this generation of self-driving vehicles.

that intersection's turning lanes are delineated by dotted lines. this isn't unique, but it's interesting to me because dotted lines can sometimes be more difficult to see than solid lines (especially in certain lighting or weather conditions, or when there are debris on the road). for example, i remember lanes on stretches of 101-N marked with faded dotted lines and no reflector dots. these lanes were impossible to see under wet conditions and the sun's reflection. drivers were forced to either guess where the lanes might be, or to follow other vehicles, but we could still proceed safely. how would a driverless vehicle respond?

further, some human drivers completely ignore lane markers even when they are perfectly visible. in india and some central american countries, for example, driving conditions are like the polar opposite of suburban SV: lawless. yet in my experience, driving there is not without rules; it's just that the rules are unwritten. and though this is an extreme analogy, it led me to an interesting question: if self-driving vehicles can't safely navigate the crowded streets of mumbai, how comfortable are we giving them free reign in the US? or perhaps should we exclude them from certain roads until they can?

the main point i'm trying to make is this: the current generation of self-driving vehicles has not developed (whether by feature or flaw) the level of intuition of an experienced and safe driver. they are quite literally like student drivers whose instructors have a foot above the brake and a hand on the steering wheel. and while it's conceptually possible to create safer roads by eliminating human error, i'm not confident replacing humans with a bunch of robotic student drivers is the best solution. i'd feel much safer as a passenger in a vehicle driven by someone or something that's A) primarily concerned with my safety (and not corporate liability), and B) knows what to do in unexpected or unpredictable circumstances.
