Do self driving cars make you feel uncomfortable?

Not really, but I think that before there is full scale adoption of the technology certain questions must be answered. 1. How is ultimately responsible for any accidents while in self-driving mode? 2. How will upgrades be installed (I am very leary of an automatic upgrade)? 3. How will the bridge period between autonomous driving and non-autonomous cars react(it takes about 15 years before 90% of the cars will have current technology, example would be there are still non ABS brake systems on the road)? Another point I would like to make is, I drove a car recently with partial sensors, (collision avoidance, and lane change warning) well I went a visited a friend outside the city, and had to take a detour down a gravel road about 1/2 mile (1KM). When I left I got an error message that said both collision avoidance and lane change warning was off-line. When I took it back to the dealer, they looked at the car and said the gravel/muddy road that I drove on obscured the sensors giving me the off-line warning. Now currently most drivers use to driving cars without autonomous technology, fast forward 10 or 15 years from now will the drivers then know how to drive with out autonomous technology. I think the sensors need to get better before that happens, but all and all, I can't wait.

Tech companies and car manufacturers are spending billions to get self-driving cars out on the road. They will be better and more efficient at driving than we consequently drive on the roads will become a great deal safer.

One of the biggest hurdles to the widespread adoption of autonomous vehicles is that we cannot simply trust them and we have a thought of ceding to all control to a machine which makes us nervous.

A survey last year done by AAA in which what we have found is consumer welcomes enhanced features of autonomous technology such as adaptive cruise control and automatic braking. The lack of trust is not putting off car makers. They are now locked into a race with technology companies to roll our first in self-driving cars. Though there are many benefits too many people have long commutes and traveling in a driverless car could enable them to use time productivity.

No, self-driving cars do not make me uncomfortable. Let me approach that in two ways, when the car is mine and when the car is somebody else's.

I currently drive a Tesla Model S with Autopilot. That's not self driving and those who use Autopilot know that you have to be ready to take over. That should give us pause about a fully self-driving car, but practice with the limitations of lesser technology take the weirdness away from the car making some of the decisions. I am confident that regulators will not allow self-driving cars unless they are proven more safe than human drivers. I trust statistics. (And my driving is not getting any younger these days.)

When the car belongs to someone else, I am also encouraged by the role of regulators to ensure that the car is safer than one with a human driver. Right now, I have no way of knowing if the oncoming car is driven by a drunk driver, or one who has fallen asleep, somebody texting, or one intent on vehicular suicide.

Of course when we have lots of self-driving cars, all talking to each other, then the accident rate will really plummet. That makes me comfortable.

Initially it must be making you uncomfortable, But given the human nature we quickly adapt to the situations with time. You may be occupied with some important tasks while being an occupant in the car instead of driving yourself. You can complete an assignment, read a book or browse internet or more importantly take rest while the vehicle safely transports you to your destination. That is the intent of developing driverless cars to make things comfortable and safe while delegating the driving routines to the computers and machines.

Contrary to industry propaganda and, consequentially, popular belief, "self-driving" cars for the mass market are a chimaera. A marketing device, like putting girls with silicone knockers on motorcycle mags.

Thus I won't have to witness the presence of millions of buggy 50-kW robots - or even of some - on public roads in my lifetime, and the answer is: no.

What is the deepest any amount of sunlight can reach in the ocean?

It is usually accepted that 200 metres is the extent of how far sunlight can travel below the surface.At this level everything lives in the dark. Some creatures down there have adapted to life in these low level light and some even produce there own headlamps. These creatures not only have to contend with the lack of light, but

Can you lift the Earth in space?

Other answers, such as Mr Consiglio's, go some way to answer your question.I would, however, point out that while gravity is responsible for weight, weight is a product of mass under the force of gravity. Under that logic, therefore, the Earth is weightless in space (as you infer in the question
