Again, this works in the US with big suburbs where everyone has a parking lot with an electric outlet. In other countries (like good old Europe), where most people live in apartments and there is just no way you can plug your car at night, it doesn't work.

I live in Europe, in an apartment, with my car in an underground garage 20 meters below. There is an electric plug to charge my electric bike, and I look forward to also charge my Tesla XYZ in a few years...

It won't be the government that pushes people towards autonomous cars. It will be insurance companies.

To be precise : it will be the lower price of insurance policies that will push many towards autonomous cars.

However, smart insurance companies will see this as a dangerous erosion of their market, and will probably fight against this...

Not always. Jeanne Calment was once asked what the secret of her long life was and she said that she thought that cutting down her smoking at the age of 96 had a lot to do with it.

From the very same Wikipedia page :

In 1896, at the age of 21, she married her double second cousin, Fernand Nicolas Calment, a wealthy store owner. (...) His wealth made it possible for Calment never to have to work; instead she led a leisured lifestyle, pursuing hobbies such as tennis, cycling, swimming, rollerskating, piano, and opera.

Don't you think it also helped ?

The second thing would be logicals and overlayed directories. They worked like a stack of transparencies like the human anatomy entry in an encyclopedia. The base layer would be a read only version of the operating system. Above that would be a writable layer. Above that, for development users, would be test versions of new OS elements. Regular users wouldn't see these layers. Above that would be applications (read only) with a writeable layer above it. The purpose of the writeable layer over the read only layer is to trap attempts to overwrite system files.

Isn't it what UnionFS offers ?

assuming electricity prices remain constant.

That's obviously a big assumption; but an even bigger one is that the price difference between day and night remains constant, which will definitely not be the case as soon as a significant part of electricity consumer start charging at night...

5 cents is low. Most time of use differentials are much higher. In my area, it is 14 cents. At that rate, it works out to $1.40 a day. This is $511 a year return on a $3500 investment... pretty good return.

Yes, but your scenario relies heavily on the price difference between peak and off-peak ; as soon as a significant part of the users start doing this, peaks will be smoothed, and the price difference will decrease.

I fully agree with you. And a few other interesting use cases for self-driving vehicles :

- Kids can use it (for instance when you don't want to have to pick up your kids at their soccer training)

- Older persons can use it when they are not able to drive anymore

- When you get home at 3 AM half drunk

The fact that English has become the word's language has nothing to do with its ease of learning.

Care to explain why ?

You would certainly agree that a language that is hard to learn has fewer chances to be used all around the world ? Hence, being easier to learn surely helps (even if there may be other reasons).

It's just a pity that the world's de-facto common language (English) is so hard to learn well...

I disagree; English is relatively easy to learn, therefore it has become the world's de-facto common language.

Besides, any language (except maybe Esperanto ?) is hard to learn well...
