At certain times of the year, you can be driving out of one of the
tunnels and be blinded by the sun. It's quite a shocking thing to be
caught unawares of this phenomenon. Your best bet is to slow down and
look at the dots on the road, and try not to hit anything in front of
you. I'm going to have to start documenting when this sun blinding
occurs - date & time.

One of the tunnels under the Welland ship canal has a very elaborate
lighting system that reduces the shock of going from bright sunlight to
a dark tunnel and then back into bright sunlight. They have bright
lighting  at each end and then reduce it in the middle. It would cost a
ridiculous amount of money for power to have all the lights on all the
time so they taper the brightness in a way that your eyes have time to
adapt and then crank it back up so you won't be blinded when you emerge
from it.

That's a pretty trick setup. Our tunnels aren't that long so we don't
have gradient lighting - or do we? I never really noticed the lighting -
but I'll check it out.
When I was a kid, I'd always hold my breath while going through the
tunnels. I got pretty good at it. I wonder if I can still do it. I'll
have to check that out too.
