Indeed. There are 3 criteria studied to classify cyber threats: Confidentiality, Integrity, Availability. While it is possible, an integrity attack on safety related systems is very difficult to achieve, while an availability attack is much

Absolutely yes. There is a goldmine there waiting to be found. Most appliances in our modern world are total maintenance disasters, especially compared to pre-industrial civilizations.

Not the next big paradigm because it already exists for critical software and UI [1]. For verification purposes, thinking in state charts at design level is essential. The fact that code does not reflect easily this model is not an issue pr

This is very true. However it also creates weapons that are sitting around waiting for justifying their existence. Unless you really need these weapons (and I absolutely recognize it can be the case), shouldn't we use the money on othe

It is a topic that fascinates me. Would you have a more extensive read list to recommend (graduate textbook level)? Note: Without decapitating rats, if possible...

I confirm. I grew up near the Atlantic Ocean, in an area of high current. It is something that was taught to us as teenagers.

Metros are the only driverless systems in mass transit so far. There are some ongoing projects for driverless freight but I consider that it is not relevant to this particular discussion. I don't want to sound obnoxious but driverless

I can really understand your frustration on PTC. PTC is a problem of ROI for operators. The incentive is apparently not so great, so it will take decades. Also, and this is frequent in rail, any complicated solution that will leverage the e

It is a very nice sumary and I agree with you. Thanks for that.

You confuse technological advances and safety techniques. These are very different things. Safety techniques are theoretical principles that are used to keep technology safe. Typical examples of safety techniques in systems design are: read

Aerospace is the /absolute/ leader for driver assistance. They have decades of experience, especially in the field of ergonomics and brilliantly crafted semi-automated procedures[1]. But in the end, we all accept the risk of ridin

Planes are not driverless. This is what I am talking about.

Sure, and this goal can be reached without driverless. I am really supportive of driver assistance. The point I try to make is that bringing driverless on top is a challenge that seems to be underestimated.

No problem at all, I was half expecting such reaction. http://www.uitp.org/sites/default/files/Metro%20automation%2... There has been 1 accident in 30 years attributed to driverless rail mass transit control

You are correct. I will edit and add some supporting references. I don't know where Elon gets his numbers from, but according to EN 50126 practioners, human error is in the range of 2E-4 / 1E-3 whereas safety functions are classif

Driverless trains so far are only used in mass transit so... I am afraid these are daily experience. For the second part of your argument, there are multiple problems, again backed by examples in the railway world. First, a politician will

"Huge"? Are you so sure? First, you do not need self driving car to achieve 5x improvement. Good driver assistance systems will get you there. Then, put yourself in the choose of the politician that is authorizing this technology

For the first paragraph, I don't understand the logic behind your comparison between a train failure mode and a car failure mode. However your assumption on braking capability is wrong and it is a crucial point. It does not matter how

The requirements for safety in railway are well defined in EN 50129, EN 50126 and EN 50128. You will be required to meet these standards for an ISA (independent safety authority) to give a positive report, and then for the applicable transp

No personal opinion here. It's just facts from the only ones around who have done this before. Your argument is flawed. We have also been there. Here is the catch. You are willing to take the risk, but society as a whole will not. As

The only industry to have produced truly driverless public transportation systems is the rail industry. Not aeronautics. Rail systems happens to be my business and what I read here makes me very worried. I don't think the majority unde
