The truth about self-driving, the best way to do it is on roads made just for it. I don't think the government has the money for that.

Michigan is putting in a special autonomous vehicle corridor from Ann Arbor to Detroit, it will be a few years, but it should be an interesting test to see if it's worthwhile on a larger scale.

Ridiculous! Why would you ever need more than the 48 states?
....oh, yeah... never mind.
You need more than the 48 States because Ford sells worldwide. You need to add all six territories (including Washington, D.C. unless Congress prohibits autonomy there), and especially my own, Puerto Rico. If Tesla can sell Model S, X, and 3 here without a single service shop, Ford must sell the Mach-E, too, through our many dealers.

I've read an article once of scientist, not programmers, that said full autonomous driving is an impossible task to achieve, not talking about the 25 km an hour airport shuttle drives, for the exact reason that you've just mentionned. To many choices for an AI can occur in an instant.
This is one more reason why automous vehicles need "V2V" communications so they can organize the traffic between themselves and not need a master computer manager all the time.

I meant the one where you can call your car and itll reverse out of the spot without you in the car
That will need a better vehicle to fob communications to locate where you are standing. Probably add a Doppler shift discriminator to calculate distances until the vehicle is less than three feet away from you to decide when to stop (and give you time to move away if necessary).

Yes but in this case since your phone is the fob. Using bluetooth it should be able to. Tesla had displayed this not sure if they implemented it but with 2 kids trying to put them in a car seat this would help.

I read that article. The problem was actually the timing. So the way Tesla is trying to do autonomous driving is by analyzing the images obtained via camera. When cameras obtain the pictures around the vehicle it had to stitch the images together to create a whole scene, analyzing and then decide. By the time the stitching is done and the cpu decides on a course of action the images have changed. Its a very difficult process due to timing and when you are dealing with emergency situations every ms counts.

I think the hardware will get there (sensors, CPU, memory...) But like what Raymond said above, we really need V2V + SmartRoads to be able to have a safe experience. That will be a much larger and harder under taking having a standard all the countries + manufacturers can agree on. Everyone will maneuver themselves to the top to use their standard so they can have the upper hand. In a smaller localize environment, it is more likely to happen. Much easier for Singapore to dictate it happening than it is for the USA. Just look at the adoption of high speed internet. It would be interesting to see if it happens in our lifetime (20-30 yrs). Still waiting for the flying cars & jet packs.

Latency is a problem for humans, too. From what I gather with car compute ability, it's a bigger issue for humans than for cars.

Relying only or predominantly on optical cameras for road vehicle autonomy has much more serious issues. They can't see through fog, heavy rain, or while covered in snow, dirt or mud. This is especially an issue for a vehicle relying on a budget level setup like a Tesla, which lacks a way to clean the camera (e.g. for mud) or to heat it (e.g. for ice/snow).

The MobilEye test vehicles (and Tesla's) have several outward facing cameras on all sides.

I believe the MME only has mostly downward pointing cameras for the surround view bird's eye view.

I'd be glad to be wrong.

Like the Hyuandai

This is cute but if you need this feature you'll be too close for the neighboring car drivers and passengers to get in and out -- dent city!

It would be more for my own garage sometimes its tight

Understood and expected. Computer cars canā€™t be timid anymore than a teen entering the highway during their learning curve can avoid hurling themselves into situations they canā€™t be 100% certain they will survive unscathed.

Recently watched the Jerusalem video. Very impressive.

However that was one ā€˜autonomousā€™ vehicle on the road acting aggressively against human drivers. Soon critical interactions will happen when ā€™autonomousā€™ cars will be more numerous and find themselves acting aggressively with one another. Throw humans in the mix who are unaware the other cars are ā€™autonomousā€™ who expect they will behave as human drivers would. Add others who are aware and believe the programmed cars will always give way. More who are aware but believe the programmed cars wonā€™t give way and thus will make unsafe stops, decelerations, lane changes, etc. as a consequence.

Can all the problems be fully sorted with time? Perhaps.

However the human experience with engineering and software development should give pause to those who think the journey will be smooth.
Your concerns are valid, you might be interested to search for Mobileye and RSS. RSS is Mobileye's safety rules embedded in their self-driving engine. they are remarkably concise. There is a lot of information that may start to put your mind at ease. Here is as link to their site, (the more interesting information if lower down on the page): https://www.mobileye.com/responsibility-sensitive-safety/
