Elon Musk is n’t afraid to speak his mind — and it always feels like he ’s about to switch the world . So when the Tesla , SpaceX and PayPal billionaire sat down with Nvidia ’s CEO to talk abouthis self - driving cars , we listened cautiously . ( Not because he always delivers on his promises , heed you . )
Here ’s how Musk described the hereafter of self-directed cars — a time to come he believes Tesla will help usher in within the next few decades .
The chase is transcribed from an interview between Nvidia CEO Jen - Hsun Huang and Elon Musk at the 2015 GPU Technology Conference in San Jose , California . you’re able to find out the original recordinghere . We ’ve contain the liberty of bolding our favorite dividing line and stripping out the give-and-take between Musk and Huang . Sorry Jen - Hsun !
Elon Musk:
I do n’t think we have to worry about autonomous cars , because that ’s sort of a minute form of AI , and not something I think is very difficult to do actually — to do autonomous driving to the degree that ’s much dependable than a mortal is much promiscuous than people imagine .
I conceive it ’s just operate to become normal . Like an lift . They used to have lift operators , and then we developed some simple circuitry to have elevator just come to the level that you ’re at , you just press the push . Nobody need to operate the lift . The car is just go to be like that .
You ’ll be able to tell your cable car “ take me home , ” go here , go there , anything , and it ’ll just do it .
It ’ll be an order of magnitude safer than a person . In fact , in the distant future , I guess it ’s probably going to be … hoi polloi may illegalize force back railway car , because it ’s too dangerous . You ca n’t have a individual driving a two - ton end machine .
If you may matter on not having an accident , you may get free of a Brobdingnagian amount of the crash structure and the airbags … We ’re a very long elbow room from that , because there ’s always going to be some — for a very long time there will be some legacy auto on the road .
And it is important to just appreciate the size of the automotive industrial base . It ’s not as though when somebody earn an self-reliant car , that suddenly all the motorcar will be sovereign . There ’s two billion of them . The total phone number of cars and trucks on the route is two billion and mounting … The capacity of car / truck product is about 100 million a yr .
So if tomorrow all car were autonomous , it would take 20 years to replace the fleet , assuming the fleet stayed the same size of it . Arguably it could get little if thing were autonomous , but still it ’s maybe 15 long time or something and it ’s not all going to transition immediately . It ’s going to take quite a while . And it ’s the same for electrification of motorcar . Changing that industrial base to be electric — if all cars tomorrow produced were galvanizing , it would still take 20 years to replace the fleet . And right on now it ’s 1 percent .
You kind of necessitate the hardware groundwork , the sensorial computing foundation , and then you may just keep update software . At least you’re able to with a Tesla , the features are steadily improving … we now have active sail ascendence , we use radio detection and ranging and camera fusion to track the car in front of you … it looks at the brake light , so it anticipates when the brakes are active … it ’s pass to get smarter and voguish even with the current ironware suite .
The current ironware entourage is 360 - degree ultrasonic sensors that go up to just over 5 meters . There ’s a forward camera and forward-moving radiolocation . Even with just that detector rooms we can actually make Brobdingnagian progress in autonomy . We can definitely make the railcar steer itself on a superhighway and do lane changes .
Autonomy is really about what horizontal surface of reliability and safety do you desire . Even with the current detector entourage we could make the car go fully sovereign , but not to a degree of dependability that would be safe in , say , a complex urban environment at 30 miles per hour where the lane marking are n’t there and children are run and thing could be coming at you from the side . to solve that you ask a bigger sensor suite , and you postulate more calculation power .
Where it gets sly is that urban environment around 30 or 40 miles an minute . Right now it ’s fairly easy to deal with things that are below 5 to 10 air mile per hour , because we can do that with the ultrasonics — we just ensure it does n’t hit anything , because you’re able to always brake … At 5 - 10 miles per minute you’re able to stop within the stove of the ultrasonics .
Then from , let ’s say 10 miles an hour to 50 mile an 60 minutes — that area in complex suburban environments — that ’s where you could get a lot of unexpected matter happening . lease ’s say there ’s a route closure or a manhole cover unfastened , children act is a big issue , bicycles … once you get about 50 miles per hour and you ’re in a throughway environment , it receive sluttish again . The set of possibilities is much reduced . main road cruise is well-fixed , low speed is easy , medium is punishing . Being capable to recognize what you ’re see and make the right decision in that 10 to 50 miles per hour zona is the ambitious share .
But , and this may sound a little complacent , I almost view it as a solve trouble . We know exactly what to do , and we ’ll be there in a few year .
We ’ll take sovereign railcar for accord in quite a shortsighted period of time . It ’s amazing how well-off you get , and how quickly you get comfortable with it .
From the stop at which a car is definitely safe than a individual , there ’s a least another two or three years after that before regulators let it to be the guinea pig . They all want to see a large amount of statistical substantiation that it ’s not merely as secure as a person , but much safe .
So I call back what you’re able to do is run it in shadow mode , and essentially say “ Okay , this is what the information processing system would have done in all these circumstances , ” and was there a crash or was there not ? Like what are the false positives and delusive negatives ? Then achieve a turgid population chemical group , and make a really clear statistical argument with the governor , and then they ’re going to digest that , take note it for a while , see if they agree with it — and then I mean they will , because the evidence will be overpowering .
I suppose when it come to public safety , there ’s an tilt for being quite cautious and pass water sure that things are hunky-dory before there ’s a modification , andI do n’t think it ’s the case that right now that there is a fully autonomous organisation — and regulator are not approving it — that can be a substitute for the great unwashed . But there will be in a few years .
I think [ protection ] becomes really important when the cars are full autonomous . The style the cars work properly now , every system of rules in the car , it ’s take , could have a mechanically skillful nonstarter of some variety , or a rudimentary logic nonstarter . you may always overwhelm the braking with your foot or overwhelm the steering cycle with your hands . But when there is n’t a steering wheel or a brake pedal or something , then it ’s really , really dangerous .
Even as it is mighty now , where we spend most of our time on is that it ’s very hard to do a multi - car plug . If you have lineal access to a car , just like you ’ve got lineal access to a information processing system , you’re able to do a lot of things to it , but that ’s less of a headache than somebody being able to hack an arbitrary car or multiple cars . So that ’s what we focus our energy on . In that way it ’s a lot like a mobile phone phone or a laptop computer , you focus on making certain that there ca n’t be a organization - wide hack . So we put a lot of elbow grease into that and we have a good deal of third parties try out to set on it .
And then sure division of the railway car , at a very fundamental level — like the drive unit controller , or the steering accountant — have an extra degree of security . So someone may be able to hack something that ’s cosmetic , but it ’s much hard to hack something that ’s really physically serious . You may be able to display a funny message or something , but you wo n’t be capable to control the steering or the motor .
A lot of people think of us as the leader in electric cars , butI think we ’ll also be the leader in autonomous cars … at least independent car that multitude can buy .
We ’re going to put a lot of effort into self-governing drive , because it ’s going to be the default thing . It could deliver a pile of lives .
When it comes to AI , I ’m not really distressed about something narrow like autonomous railcar or like a smart air conditioning unit at the sign . It ’s the deep intelligence stuff where we call for to be cautious . I think there ’s many different likely layers of artificial intelligence , and it ’s odd that we ’re so close to the advent of AI . It seems strange that we ’d be active in this time .
I just trust there ’s something left for us humans to do .
