It should be a law that lights within 2000 feet of each other MUST be
synchronized.

In which direction?

the direction i happen to be going in at the time.


Just remember kids that lights that are synchronized for 35MPH are
also synchronized for 70MPH.

I wonder if that's really true. Sounds logical.

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. If light B turns green
and then red twice in the time it takes a 35 mph
car to get there, then it is sequenced for 70 mph
also. Obviously, only even numbers of changes
will sequence for 70 mph.
