Are cars built with computer controls?

I got into an argument with my dad about whether or not you could hack into a cars breaks. Do cars really have computers that operate the controls based on user input? Also if so, would it be possible to hack said controls?

Depends on how old the car is. Some newer cars have everything controlled by electronics, but this is a relatively new development. All cars after 1996 have an engine diagnostic system called OBDII which allows one to *read* state information, but not control it.
