yes, running it till it shut off was very bad. On the highway, i didn't realize it was overheating until last second...started to get off on exit ramp and it died. Second time, my gf was driving the car and she didn't realize/care that it was overheating.
Maybe I'll finally learn my lesson. I killed my first car (89 Firebird) by letting it overheat.
It won't happen again.
Thank god Chicago has public transportation!
