No driverless car is safe until all cars become driverless and communicates using computer protocols. You won't need so many sensors once people are not allowed to drive. Then you no longer need to sit in a car with a huge steal frame that weighs a ton or two.

Going to be many years of mixed driving. I would think though that the communication package may be a retrofit. Not that expensive and it may provide some help to the human as well as to the computer.

I agree driverless cars cannot reach their full potential until virtually all are...but they will still not a lot better than the humans.

So, when anyone with a laptop and a cheap SDR can cause a massive pileup?

It is relatively simple to protect processors from hacking.

At one extreme you require that the physical package be changed.

At a little less you require physically loading the package.

At a little less you require that the package be encoded for that specific machine.

then general encoding. Requiring that code only be accepted from preset sources you call.

Cars will use a set of these. Certain things will be very tight. Others rather loose. Likely your entertainment systems will be vastly more compromise-able than your mechanical systems.

But it reeally is not a difficult problem...just don't take the easy ways.

Driverless cars will not happen in most places.

What will happen is an "Autodrive" mode used while a driver is in the seat.
Same with big trucks.
It'll be safer, but there are some people like me who like to drive. So we'll get to do our thing, too.

I would imagine they are both heated and/or self cleaning.

Or the road is fully covered in snow and there 4" deep ruts that the car now has to navigate ?
Ruts would be something it could easily follow, undriven snow on the other hand could be an issue without precise data or it's precise location. That would require GPS or preloaded terrain maps. The original tech in a Tomahawk missiles followed a terrain map they had loaded into the missile. Once it's fired it can be completely autonomous. There is famous quote from reporter and to paraphrase "it was going down the street and made a left turn".... LOL

I know the technology for driverless vehicles is just now really developing ,
Development started more than ten years ago. It's taken that long to get to the point where it can start going mainstream.

Seems like there is issues with it. Although, they are working out solutions.

Many of these companies are predicting 3-5 years. If that really is the case we are no where near the "infancy" that many including myself think these features are. I just can't see 3 years from now, the driverless car being mainstream, except for in very high end vehicles. And even then it seems like a stretch. For one to be released in the 2020 model year, it would currently need to be under design. Meaning all the issues have been worked out and it's ready for the masses. For instance, I'm a designer in the auto industry and currently I'm working on the interior for the 2020 GM full size SUV.

Just saw this article about self-driving buses. There's no question in my mind this technology will go mainstream, the question is when?:

I think autonomous vehicles are a horrible idea! It's going to create a generation of less skilled drivers, that are too dependent on autonomous technology. Computers are known to glitch. What happens when it glitches and the person in the car doesn't react on time? If snow or ice build up on the radar sensors? That car will become a weapon, killing people. Automakers are wasting their money. People want safe, reliable transportation. With affordable options, and the more high tech these cars become, the higher the price tag, and maintenance cost.

The person does not react. The AV protects itself. Glitch will happen but will generally cause nothing more than a safe stop.

Build up on sensor the AV will not run until they are cleared. AVs test all their systems before they will move.

The things will hit the road an order of magnitude safer than a human driver. The device will have very high reliability and very little maintenance cost. Virtually nothing will wear out except perhaps a few of the sensors which have moving parts.

Once underway the statistics will offer vast improvements in safety and fatality rates. As this becomes clear the human driver is likely doomed.
