If the Caro-Kann exchange leads to a draw for black why did Bobby Fischer decide to use it against Tigran Petrosian in an important tournament, and why then did Petrosian lose instead of getting this assured draw?

This is an opening white can play for a win with. There's not much theory to "learn" either, that's the point. If I decide to switch to something else it doesn't matter because it only takes a few days to learn the exchange variation anyway. Meanwhile I can be studying tactics and positional ideas and not get bogged down in theory against an opening I'm only seeing once in every 25 games or so.
I think your problem is that your bias against the exchange French is now carrying over into the exchange Caro-Kann. Just because they both have "exchange" in the title doesn't mean they're the same. And anyway, the exchange French isn't so bad either, that's another good way of avoiding theory. The Caro-Kann and French players don't want you to play the exchange variations, they want you to use the main line variations they've been studying for years so they can smash you off the board with their theoretical knowledge. Sorry, that's not what I'm going to do, and you can try to disparage the exchange variations all you want I'm not going to play right into their hands just because those openings are more "pro" or whatever.
Also the Caro-Kann exchange is helping me learn strategy and middlegame play. I enjoy having a game where each side has clear plans, and an opening that's based more on ideas rather than theory.
Black side of the QGD Exchange Variation up a tempo sounds good to me. Also I don't find conducting kingside attacks dull.
An easy draw for Black at what rating level? We're talking about 1500-1900 players here. We're not GMs, we're people who still make mistakes in our games. Personally I'd rather spend my study time on tactics, endgame, and general positional ideas rather than "The Advance variation of the Caro-Kann" or whatever it is that the Caro-Kann player is hoping you'll try against them so they can out-theory you. Maybe when I become an expert level player and am playing games where no mistakes are made then I'll switch to that.
I've consistently been between 2050 and 2150 for the last couple of years, nowhere near GM. Not even flat out master. Not once have I had an issue facing the exchange.
I would never advocate this line to anybody as a draw for Black is a moral victory. Only time this should maybe be used is if you are facing someone 300 points higher, it's the final round, and a draw is sufficient.
I would recommend the Panov, Fantasy, or 4.Nc3 line of the Advance Variation to a tactician, and 3.Nc3 or Advance with 4.Nf3 to a positional player. If you play 3.Nc3 and Black plays 4...Nd7, if you do choose to do the quiet line, 5.Nf3, then after 5...Ngf6, play 6.Ng3. 6.Nxf6+ is a joke and again, an EASY draw for Black!
You should also NEVER use rating as a basis for the rightness of an opening. 1500 players (over the board that is) are a joke. You could play 1.h4 against a 1500 player. However, why learn garbage when you are going to have to start all over again when you start facing 2000 players, or masters? There are 5 legimate lines against the Caro-Kann (actually, there's 6, even 2.d3, leading to King's Indian Attack lines, are better than the Exchange Variation), some positional, some tactical (see above). Might as well learn one of them now rather than having to start all over again once you gain a couple of hundred points.
