no no no, you are misreading causality here. The error of 5 seconds a month is between the One True Clock (the one with the pendulum) and all those silly cessium and gps dohickies.

I thought the drones had geofencing, so it should be possible to geofence the entire US and block them that way?

you mean like the time they invaded and took Washington DC?

Canada being the only country to successfully invade the US

or did I mix up my pronoun references again?

I'm curious what you consider "training", and how this would be different than a vocation-specific university degree? Which typically also includes supervised real-world teaching experience?

Hey, I hear you. And I'm sad. Because I'd like to say that the right way is to:

build infrastructure that promotes safe driving, and

train drivers to show respect for other people on the road

However, those are both non-starters in the US. So your answer, which comes down to "at least self-driving is better than those damn people" might be the one that actually works.
