Can someone answer the elephant in the room why are they developing self driving cars?
Because they can, there's money in it, and they want to, is the short answer. Driving has been de-skilled for decades now. Traction control, stability control, ABS, adaptive cruise control. All sells very well. Then there's the convenience features. From automatic transmissions to electric windows and headlight jetwashers. Those features cost a lot of money to develop and produce. Who's paying for that would you say? Autonomous vehicles are just a natural progression of this line.
Do governments want to take the human element out of driving?
I don't think they truly care as long as they get their piece of the action. Which they will.
Did you read your own post?
What are you crazy?!?!? Have you read some of what I write? Of course not. I type with my eyes closed singing very loudly in my head to block out the bad thoughts.

Nrshida, like it or not, it's coming. That pretty much set the "mandate" thing going.
Depends what you mean with mandate. If you mean an ‘an official order or commission to do something’ then no, this originates in industry and academia not government. If you mean ‘authorisation’ to do something then no, legislation always walks behind product development with an innovative content. Look at Tesla’s Model S interface. Same interactions with a phone while driving will get you fined (and rightly so). If you meant ‘mandatory’ then no, it’s optional, although there might be a point far in the future where non-autonomous vehicles are restricted to certain roads’. That’s be far far off though. A tolerant society shouldn’t stop Chalenge driving round in his Model T shaking his fists at everyone. That’d be cruel.
If you had some other meaning intended for that word then you’d have to explain further.
I’m not as arrogant or bombastic as some of my posts might make me out to be. Just this is very close to my area so I'm passionate about it. And I’ve got an allergy to people who are deficient at thinking for themselves but decide they'll think for all of us. I hate that but then we've all got our allergies haven't we?
About design and technology: look at American design in the 1950s and 60s. Was all about excitement in the future. Now what do we have? Retro design, a wish to recapture the 'better' times of the past and an ingrained fear of anything new and unfamiliar. Bit of a sad state of affairs really.
