Would you want a self driving car?

[Savonarola]

Trains seem to be fairly easy to automate completely. There is much less variance than in road traffic. If the train encounters an unclear situation or signal loss, just stop it and let a remote controller take over.

Yes, that is true.  The problem is that trains can't be just as safe as cars; they have to be much, much safer.  In the United States over 30,000 people died in automobile accidents; people are willing to risk death when they drive a car.  A train wreck, even if there are no fatalities, is national news.  People aren't willing to risk injury when they ride the train.

Your car driving you home when you are drunk. Enough said.

I love driving, it actually relaxes me, but I am also not an insecure male, so I wouldn't feel like my dick gets chopped off if I have a software as my chauffeur.

Yeah, a train seems like a much narrower problems space with radically greater amounts of control.

Planes are even more complex than cars, but have the advantage of a much more rigorous environment to operate in as far as controls on other aircraft.

They also have a much simpler environment to navigate.

No need for a self-driving car, I commute by public transportation.

Just put a sensor on the rear doors and inform law enforcement when the sensor is tampered with..

No reason I can see that you couldn't do that with the trailer of a big rig today.  No need to wait for self-driving cars.

No need for a self-driving car, I commute by public transportation. 

I'm a mostly happy public transit user, but other than getting to and from work it isn't practical in most cities to rely only on public transit.  I still need to be able to buy groceries and other large / bulky items and transport them to my home, I may need to get to areas that aren't well covered by public transit, or on evenings / weekends when public transit runs rarely.
