I rode the Bobsleds, too, and will never forget how that very last turn into the brake run banged everyone's knees *every* *single* *time*.
It was quickly replaced (using the same boarding station) by the Shockwave prototype stand-up coaster, which was also very short-lived.
Fun trivia: Epcot's original Dreamfinder, Ron Schneider, worked at Magic Mtn. as a ride operator on Grand Prix! He also was one of the park's "Mountain Men" who worked with the live lion.
BTW, I loved those old, rough-as-heck Freefall towers. To this day, I still can't figure out why they were so much scarier than today's drop rides, at least to me.
