But those rails are on otherwise off-limit tracks and 'third rail' solutions are notoriously dangerous. This system has the two rails closely spaced side-by-side so it may be a bit safer but in the presence of moisture it could be dangerous too.

It's basically a scaled up version of a slot car track.

Did you read the article? This is addressed.

Yes, I did read the article, otherwise I would not have been able to write what I did, note that the title says nothing about how the electrodes from the car connect to the road. So you could have known that I had read the article. Yes, the article addresses it, no, the article does not address it in a way that gives me a good feeling about the safety of this system in the presence of moisture. It really doesn't take a lot of power to kill a person and even though you can ground-fault-protect the crap out of a setup like this the fact is that such measures can fail and if you start deploying it en-masse in a hostile environment they will fail in large enough numbers that it will not longer be safe.

Note how industrial power is hardly ever ground fault protected because the leakage currents in the standard setup are too high already to reliably detect a ground fault.

In other words: if the system delivers enough power to electrical cars to meaningfully affect their state of charge there is inherent danger.

It clearly states that salt water in the rail only gives off 1 volt at road level and that you can walk on it barefoot.

Highways are already off-limit and notoriously dangerous.

Unfortunately, we need to accommodate the future Darwin Award winners. Besides, there's dangerous, and then there's 'the government caused the death of someone who stepped on the highway'. Getting zapped, even mildly, would distract someone and decrease a person's chances of getting out of the way quickly.
