I've wondered why many school busses that I see, have chains that almost touch the road that extend from the middle region of the bus.

Also, its not on all buses. Do you have an explanation to this?

Static discharge...

I've never seen or heard of these chains. I'm sure it's not static electricity, since I've never had a problem with static electricity on my bus, and we have no such equipment.
The Chains might be a part of the safety equipment. On my bus, there are "Safety Hangers" which hold the Drive Shaft in place if it breaks. The drive shaft is a big honking piece of steel, and if it were to break and go flying it could kill other drivers, or break through the floor of the bus.
Our safety hangers are solid steel "U" shaped braces, though, and not chains. Still, I'd be willing to bet that the chains you've seen are doing the same job.

Many busses have an "auto chain" system that allows the driver to filp a switch and the chains fall down and under the wheels for more traction in snow.

It's a system that is used in areas that get snow on a regular basis. I don't really know how it works, but I know it's chains for traction just like chains on a car - they're automatic somehow, but that's all I know. They had them when I lived in Colorado (and presumably still do). I haven't seen them here in the Seattle area, but then we seldom get any real snow.

They are not for static electricity or lightning. Why do you people just make stuff up? They are for use in the snow. Here is a link to a youtube video of how they work.

I would think that they are on there to ground the bus and discharge the static electricity. So when little Johnny get out of the bus he doesn't get shocked and become afraid of the bus. good luck.

Most likley they are snow chains, they look like a ladder of chain.
You would also see them on commercial trucks.
Chains require the vehicle be driven slow, no more than 35mph.

So if little-Timmy gets run over, he's almost guaranteed to get hung up and dragged for 4 or 5 blocks. Like Martha Stewart says: "If you're gonna do something..."

The chain is there to dissipate static electricity

safety in case they get hit by lightning or another large jolt it will discharge to the ground.
