I am one of the believers that self driving cars will one day make roads safer. I just think that the technology we have now that keeps getting called "self driving" is not there yet. If it requires the driver's full attention to keep things safe but also makes individual drivers feel like they can be a little less attentive then we don't really have a very safe situation on our hands.

When I say that the technology makes people feel like they can be less attentive I really do mean it. There was the SF tech worker who was playing candy crush or something when his Tesla smashed into a barrier on the highway. I have friends who own Teslas and talk frequently about how they like taking them on road trips because they can relax a bit more and pay less attention to the flow of traffic (it'll brake for you!!! they say). In a world where these cars have to share the road with human drivers and drive on roads that are under construction or in poor weather conditions I just don't see how we can say this is safe.
