I have never driven a manual car in my life, sems like an absolute waste of effort. Manual cars are pretty rare here now I think.

I just checked, and sure enough:

It should be obvious that a person that dislikes having the car shift for them is going to dislike having the car drive for them even more. At least I would think that's obvious. For some people a car is nothing more than a transportation appliance, Americans in particular are lazy and just want to get where they're going, other people like to drive. Another symptom of this is that the vast majority of cars are incredibly boring and nondescript, the market seems to have settled on the generic CUV design, virtually everyone is making them and they all have comically enormous grills and emblems because that's about the only thing that differentiates the brands.

I love automatic and I consider myself a bit of a driving enthusiast.  The dual-clutch transmission in my car can shift faster and more efficiently than any manual can, is smooth as butter when it comes to modest acceleration, and reduces the need to think about shifting gears in traffic or around the city.  I disagree that having an automatic means you can get distracted; on the highway, a manual can sit in 5th or 6th gear just fine whilst someone decides to text and drive.

Almost impossible, once they get across the border or near your coast on a sinking ship without papers what are you going to do?

Barring some fundamental change, ie. singularity, the most humane solution would be an evolved version of the Australian solution. Buy land from some thin populated third world country and create a colony for refugees. They'd have to rip up a ton of post WW2 and EU treaties though, which is never going to happen.

It's not like you have anything better to do.

The infrastructure could be as simple has having posts with transponders of sort on them or even just QR codes or other subtle markers that are easy to pickup by automation.    Ideally it should be something passive that requires no power since there is no power along most highways, at least not low voltage.   GPS on it's own is not accurate enough especially at driving speeds and required reaction times. Ex: driving 100km/h less that a foot away from other cars, civilian GPS is just not accurate enough to make that kind of judgement in real time like that.

The issue with self driving as is right now is it relies on lot of things to be perfect, such as the road being very clean, no pot holes, no snow, proper lines and signage, etc. That is not a very typical road at all. Highway 11 for example is usually snow packed, and most roads are full of potholes that you need to avoid.

Let me know where you drive 100 km/hr one foot from other cars.  I want to avoid the area.

Afaik GPS is not used directly for guidance or navigation.  The information is melded with rate and acceleration sensors and the radar sonar and vision sensors to get an estimate of where the car is.  Much like human drivers do.  And as prior posters said, because the details are different  the successes and failures are different.

Ideally you are not actually going 100km/h once you are at 1 foot but in a typical driving situation you can go from 100km/h to having to slow down, stop, make a turn etc and in any of those situations you could be a foot away from other cars in the stopped state or while turning as there may be other cars turning too.  These are all split second decisions that you do passively while driving, but automating this to be accurate 100% of the time is not easy. On the 400 series highways it's also not that uncommon to be bumper to bumper, though it's typically at like 2km/h.  But I have been in such traffic when it was actually moving at the speed limit. It's a little unnerving. I wouldn't want to be driving in that myself, I was a passenger.
