An interesting bug/oversight.
Tried driving from Talos to Bridge, skipping Laurion. Got from bridge to Santorini. Power in rover running low. I drive to central compound, nearly out of power. I get halfway through "Park Rover", when I run out of power.
There is no option to get out of my Rover.
There is no option to push my dead battery Rover into the powered Garage.
There is no option to enter the Santorini, grab a fuel cell, and then go back to the Rover and turn on its generator.
Now I have all my actions as "red" (cannot do), and despite having 11mins till Santorini is destroyed, I'm forced to Loop Now.

So what is the point of the Talos to Dam route, if you don't actually have the power to make it to Santorini, without visiting Laurion to grab the fuel cells?
