It's every problem with the existing tunnel multiplied a thousandfold. What happens if a Tesla breaks down halfway through the tunnel? You can't get out of the car in there, too narrow. Is a tow truck going to fit in there? Is it going to be able to drive 12.5 miles in reverse?
multi-car pileup and tunnel fire waiting to happen

What is going to happen when (not if) something catches fire down there?
There is a parallel tunnel for evacuating people, right? Right?
