It really depends on who is introducing autonomous cars.. You need a critical mass. You are right if people are either choosing to own a car or if car sharing is split across many different companies. If, however, there are a few global or important companies for ride sharing at a price that is competitive, it mght be sufficient that those in their 20ties and 30ties are interested, to get a critical mass.

I'll be happy to have a self-driving car when I'm really old and unable to drive.

Heh. My wife *hates* being a passenger in a car. (Not because of my driving, I'm a very good driver, clean record, honest!) I always let her drive, when we're together, because making her ride, without the steering wheel in her hands and the pedals at her feet, is just too obviously cruel. I'm all enthusiastic about autonomous vehicles, but I don't know if you'll ever get her into one. You'll probably have to get our generation into the grave before you can complete the transition.

I could have written this word for word. I only get to drive if it has been a long day and we’re far from home and my wife is more tired than me. Otherwise, my wife does all the driving and my friends mock me for it. Since I take public transportation to and from work and we are a one car family there are months where I only drive the car once.

Oh yeah - you are correct. I am very familiar with the mechanical differences. Still - computers. Computers fail. Computers get hung up. No big deal with netflix crashes. It is a big deal when the family hauler crashes because a computer gets stuck and the car fails to make a curve.

Control software for vehicles is engineered to much more exacting standards compared to something like the Netflix client. Commercial airplanes have been fly-by-wire, i.e. completely dependant on computers, for many years now. Many cars already make use of certain drive-by-wire functions, such as brake-by-wire...your life already depends on the reliability of computers more than you realize :)

Computer failures always happen.  We design expecting them.  That's why the concept of 'failing-safe' is so vital.  A train's default state in a fail-safe system is to emergency brake.  It has to constantly get a signal from the computer to release the brake.  If the control computer (typically this is actually a group of three control computers where decisions are made by majority vote to minimize errors) goes down, the train will immediately EB for example.

There's a government agency responsible for vehicular safety requirements (ABS, for example).   Have they said anything yet?
Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart.

And it begins.
https://www.engadget.com/2018/01/30/waymo-thousands-chrysler-pacifica-minivans/

1,000 cars this year. And i'd predict self driving cars to increase by a factor of 10 each year until we reach global market saturation:
10,000 cars in 2019
100,000 cars in 2020
1,000,000 cars in 2021
10,000,000 cars in 2022
100,000,000 cars in 2023

^As usual, a short article.  No footage.  No proof of a contract.  Looks like fake news that aims to boost stock prices. 

Level 4 cars will be shut down during very minor rainfall and snow.  Bugs on the sensors?  Shut 'er down.

LIDAR (what Waymo use) can already function in rain and snow.

Did you check the source linked in that article? Direct from Fiat Chrysler
http://media.fcanorthamerica.com/newsrelease.do?id=18804&mid=1

There's even a video for you at the source ;)

This is in addition to the existing fleet that you can see running today.

No, they can't operate in the rain in snow:

Level 4 also can't merge onto expressways, so there aren't many places to go other than to putter around a downtown or university area.

And no reference to which manufactures can't operate in rain or snow from that article.

I know the leaf was one of them that was sidelined, but it's running simple lane assist/follow.

Did the bikes to in front of the car to trigger the autobrake system or was it triggered by bikes behind the car?  I am having trouble seeing the benefit of an automated system proactively braking before being rear-ended.
Be the person Mr. Rogers knows you can be.

the bikes in front of the car triggered the car's brakes and cavendish was on a bike behind the car. this happened during a race so maybe not a real life issue. but still...

i saw this today:
http://www.cyclingnews.com/news/abu-dhabi-tour-organisers-blame-automatic-brake-sensor-for-cavendish-crash/

This is not a problem with self-driving cars really.  If the driver had dabbed the brakes a tad too hard the same result would have happened.
 In the real world if you're tailing a car on your bike and you're so close that the vehicle braking at all will cause you to crash . . . you're cycling unsafely.  Back the fuck off.  Drivers are unpredictable.
