The nice thing about hanging around not so bright people is that you look so smart.

Would you consider buying a moped to save on gas?


And to look smarter, those are not weight sensors. The wire is in a big circle (coil) and the metal from your car induces a bit of current in the coil to tell there is a car there.

Those sensors in the road do not sense weight. They sense metallic content. That is why a motorcycle won't trip them. Flashing your bright lights at the intersection will not get the light to change. In most areas with significant traffic, the lights are timed. Try going just the speed limit, after you've crossed one light green.

How would I enter 9 different locations ?

Yes it will - but I believe it is illegal. It thinks you are an emergency vehicle - look above the light, if there is a camara looking thing, that is probably the light sensor. I used to live on a cross road of a highway and our light would take forever - I used to flash it all the time to get it to change.

However, certain emergency vehicles have a device in them (Think fire and rescue) that does make all the lights green for them ... I think they are a certain frequency radar they turn on and BAM! Green lights from Bangor to Key West.
All the best.
