Is it legal to let the car drive if you're drunk?

Are you still considered to be in the care and control of the vehicle, or are you demoted to just another passenger? Will the worst consequence of driving drunk be to end up in the wrong place?
Mind you, that would be bad enough -- to punch in the wrong coordinates, and wake up in the truly seedy part of town to find dwarves stealing your wheels -- but it's certainly an order of magnitude less severe than killing someone unlucky enough to be sharing the road with you.

The sensors aren't good enough yet

Automatic driving is still sensor-limited. The
current generation of millimeter radars can see other cars, but not smaller obstacles like children. No way can they see a pothole. Vision systems are good enough for road following, but reliable obstacle avoidance still seems out of reach.
We, of course, are working on fully automatic driving. We have both a visual road-follower and a millimeter radar. That's not enough.
Even line-scanner laser rangefinders are too limited. We need a true 3D device. Such things have been built, but the market is so tiny (and they're so big and clunky) that they're all one-offs. It's clear that the problem can be fixed, but the market isn't there yet to do it.
I suspect that many will not like self-driving cars because they will not drive agressively enough. For example, many dislike the automatic speed-matching systems that maintain a "safe" distance to the next car because they leave too much distance to the next car. Tailgaters honk at the automated cars because they wont close the gap and the others cut into the large gap created by these systems. What the system (and safety experts and the car maker's insurance companies) consider "safe" is too tame for most drivers.
While many drivers are comfortable in taking risks, the corporate creators of these systems will be risk averse. That excessive risk averseness will hinder public acceptance.

A highway full of automated cars could run with very short car-to-car distances and good safety.
And then you have the opposite problem from the parent poster: people are terrified to speed down the freeway only five feet from the car in front of them.
How do we know this? Because there's a stretch of Highway 8 in San Diego County where they're testing magnetic guidance for this exact purpose. They have a "platoon" of cars with sensors under them, and little hockey-puck sized magnetic guides embedded in the pavement. Sometimes early on Sunday mornings you can see them whipping by at 60 mph with five feet between them.
But when they put humans in the cars, they panic.

Also, the anti-slide feature puts a lot of stress on the transmission, and decreases its life.
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.
