Knight Rider alert! Vanessa gets in the passenger seat of a Chevy Tahoe that can drive itself. Part of GM's push at CES, the company demo'd the self-driving car on the parking lot near the Convention Center. Since there's no way a robot driver can get distracted, self-driving cars should theoretically be much safer. We'd be more convinced if GM actually let this thing loose on the streets of Vegas. It's not like there's a law against that. I mean, we haven't checked or anything, but even if a cop stops the car, whose license is he going to ask for? Check and mate, pig.
