See, this is why we need to hurry up and deploy networked computerized automobiles. We won't need stoplights anymore, so this kind of stuff won't happen!
We will still need safety systems in tunnels though, and lack of those is why they shut the tunnels down. Ignore the misleading quotes about the variable limit signs not working, the real issue is the tunnel is not safe if there is a problem like a fire of fume buildup.
I think he was being sarcastic, hinting that network computerized auto-mobile's having a similar glitch would be truly devastating.
If mankind can't get a tunnels systems to work all the time, then what about our plans to introduce computer controlled cars? A glitch could wipe out millions of lives before being patched, and even then if they get patched that also introduces huge areas of vulnerability.
I'm sure a stealth program that loads onto a car and waits till a date to kill the occupants will be used by someone or a nation-state in the future.
