According to O'Neill, the mirrors would be skewed or warped a few degrees,
just enough to deflect the light off of the skylights. Personally, I think
that shutters would be a better way to go. Less likely to fail and easier
to fix if it does.

I assume that you meant to say "Cartesian grid" and that you mean orienting
the streets NW-SE by NE-SW instead of N-S by E-W. That would moderate
Coriolis, yes, but then you lose the longitudinal staightaways -- the N-S
run in the conventional layout -- which aren't affected by Coriolis.
In the geodesic grid I proposed, you'd have all the N-S streets as before,
but for each E-W cross street you'd have an intersecting pair of WNW-ESE
and ENE-WSW cross streets. You'd refer to these as simply NW, NE, SW and
SE -- North Main, NW Main, NE Main, South Main, SW Main, SE
Main. Intersections could be either "six-points" crossings or hexagonal
"roundabout" traffic circles. I favor the latter, as they would help
moderate Coriolis forces even more, but the N-S street might still go
straight through on main boulevards, perhaps with overpasses that
"leapfrog" the roundabouts for through traffic.
It's impossible to get lost on a properly implemented grid system -- every
intersection is a unique coordinate set. The problem here on Earth is that
we have more paved-over cow paths than actual planned thoroughfares and
have to build around hills and valleys and other natural features. This is
not the case in a space colony, where the streets come first and the
greenery gets laid down after.
