Where did you read that? Most traction control systems either
1) Adjust the throttle position so the wheels don't spin more than 5mph (i.e. if the gas is on the floor and the drive wheels are on ice, they only spin slowly).
or 2) They brake individual wheels to gain traction. This isn't stressing the transmission any more than normal driving. The differential is simply distributing more torque to the other wheel. And there's no way to do this without traction control or a limited-slip/locking differential. So it's not always a bad thing.

Hmmm. Traction control is a nebulous concept. All it really amounts to is some mechanism taking some control over wheel speed, somehow. "Most" traction controls work completely differently from one another.

About the only way that I can see the speed limit affecting road rage is when someone gets in the number 1 lane and feels they have the right and responsibility to drive exactly the speed limit. But usually traffic is free-flow, and you can get around them, and the moment passes.

Actually, the next generation of adaptive cruise control (or intelligent cruise control, depending on the marketer) is cooperative cruise control. In this mode, cars communicate in real time within their local area on traffic conditions, braking rates, speed, etc and adjust cruise control accordingly.
This has other benefits beyond emergency situations in that this sort of tech will suck up shockwaves in traffic, thus improving dense driving for everyone. There was a simulation paper on this a few years back that showed you didn't even need a majority of the cars to have this for these results.

(Which, by the way, is the fastest way to ensure we get good speeding laws...)
Same goes here. A computer is not motivated to tailgate the blue-hair in front of it because she's going "too slow." A computer is not motivated to cut the asshole in the Lexus off. A computer is not going to get in an accident because it was distraught over breaking up with its girlfriend.

The cruise control operates by measuring the actual speed, comparing it to the desired speed, and controlling the throttle. It can react to small changes in speed MUCH faster than you can.
If you gave it some kind of sensor to anticipate slope changes before they happen (laser range finders perhaps?), then it would be almost perfect.

A fully autonomous system damn well better have a 360 degree field of vision. That said, it still could miss the car running the red light if that car is screened until it pops out a lane to pass the guy who DID stop... but a human would most likely fail to spot them as well.
Advantage: Computer, because it doesn't have to turn its head to look.
A human being knows whether its safer to swerve into the lefthand lane or off the road.
Agreed, but not all humans pay attention closely enough, or at least not all the time. I know when I drive I always keep an eye out for which side has free space should I suddenly need it. Then if something DOES happen, I don't have to waste that fraction of a second looking around before making a move. Joe Cellphone probably isn't doing that.
Advantage: Human, under ideal circumstances. The best workaround for this is to not let the computer tailgate in the first place. It's probably a wash against real drivers in real conditions.
A human being can hear someone else honking his horn.
Computers can hear too, and parsing a honk is much simpler than parsing speech. Most of the car horns I hear on the road aren't directed at me, and the few that are have a variety of meanings. Could be a buddy in the next lane, could be someone telling me I left my turn signal on, could be someone is mortally offended by the bird shit on my car. If the computer can't figure it out, it could always ask the driver.
Advantage: none really. If the computer can't figure out how to respond, it will have made such a determination long before the human has had a chance to figure things out. At the very least, it'd be nice if the car automagically lowers the volume of the radio when people start honking.
A human being can see a "Deaf Child" sign.
ID tags or beacons can be placed under or near roads to serve as electronic signs for the car. They could even be mounted to the same poles as the human-readable signs just to keep things neat. Sure they don't exist now, but it's hardly a technology problem. Even simpler, we could just paint barcodes right on the street, which the car scans as it rolls by. Paint them in infrared and the humans don't even have to deal with them.
Advantage: none. Both human and computer should be able to figure out where they are and what they are supposed to be doing, if appropriate markings are in place.
A human being can tell whether the road is wet.
So can electronics. Detecting water is something they're reasonably good at. A diligent monitoring of ground and weather conditions could even keep the car watching out for black ice, which tends to sneak up on even the best drivers.
Advantage: Computer. A human in a heated cockpit simply will not know when they go from a road warm enough to maintain rain or slush to a road cold enough to sustain ice. Even without an autopilot, a friendly warning that icing conditions are present would help an awful lot of people.
