Perhaps sometimes but not always. Take for example a lights 35 miles apart
that is to go green at one hour intervals. If you drove at 70 MPH you would
be a half hour early at each light. That same analogy can be applied for
shorter distances and shorter times.
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.
I've not taken any readings over a period of time. However, I do remember
one time I was hauling through Ohio, on the way home from Indiana. It was a
warm summer day, and I was running the AC here and there to take the edge
off the heat. The MPG went from about 20 usual to about 17.
I didn't run the stats, how much more it cost, or how shorter was my range
on the tank of gas. However, I do believe that if I was trying to escape
Hurricane Katrena, I'd have been wise to leave the AC off. Too many people
running out of gas. Don't want to be one of them.
id like to get a toyota corrolla ,,,for the mileage , but im 6"5" and
none of the small cars have enough head room. my grande marquis gets 18
on the highway 13 city.
