Of course it isn't true. It depends on how many sequences of off and on
occur when going 35 and this depends on distance between lights. If
light A turns green while Light B is red, and Light B turns green just
before the car get there, typical of intown lights at every block, then
the person going 70 mp has to stop at light B until a guy going 35 catches
up.

OK, then let's try 105 and see if that works. Any volunteers?
