Is it a typo or does an Anti-Theft System 2 do something more than a normal Anti-Theft System?

Here's some interesting options, baby!

If I remember correctly, it's a copy-paste error from SR3 where the basic anti-theft system used to come without the electric shock.

Zang!

Very nice.. one of the players in my campaign is a little too fond of stealing a car whenever he needs to go somewhere

There was also the option of a self-destruct, for that sociopath with an expense account.

Or if you figure it's going to turn into Christine.

Well if the right kind of AI were to set up shop in the cars node...

Depends on the AI, depends on the car. You could end up with Christine, KARR, or KITT.

If you think your car might turn into KITT, blow that thing up. That AI was well on its way to becoming HAL. I figure it had another dozen episodes, tops, before it decided that it didn't need Michael any more, ran him over, and did its own thing.

Hell, KITT was already the star of the show already from episode one.

That cause you petty humans can't stand the allure of a red light changing in intensity. Examples are manifold.
