There are many pleasures associated with riding the new R143 subway cars along the 2, 3, 4, 5, and 6 lines, but even something good can use a bit of tweaking. Reader David sent us his proposal for making things a little more straphanger-friendly: Why not show the time twice, at the left and right, of the LED screen, instead of being justified in the middle and therefore very difficult to see past the poles and people's heads? It's so obviously brilliant, we don't see why the MTA wouldn't be able to make it easier for us clockwatchers while taking the subway. Of course, it probably would take two months to reprogram the LED scroll, so what do we know?
