I think it is a little more complex than you think.
I've seen it done, and done it myself. Does it work if the party is outnumbered by 3:1 or worse, and you insist on getting ALL of the enemy at once? No.
But then again,
neither does fireball, at that point!

They have to be in a straight line, 5 feet wide.
Not
exactly, they don't. Lightning bolt CAN be cast on diagonals, and so forth. And if the opponents are Large, that makes it even easier - aim for the "back" half of most of 'em, and you have even more breathing room WRT your own fighters.
Plus, with a preplanned tactic - every fighter delays until after the "big guys" have gone; they then full attack ... and 5' step AWAY. Even more room to fit that LBolt in, when your (also delayed) action comes up.

I'd like to see you arrange that so you can get off the lightning bolt without roasting your comerades or dinging just one or two.
Depends how greedy you are. Fireball seems, when placed to avoid comrades, to get an average of 2-3 enemies, uless used at extremely long range. 4-5, then.
If you insist on getting 6 or 8 enemies with your bolt, then yes, a comrade will be in the path of the bolt. Of course, that may not matter - in one campaign, I was a half-celestial, and the wizard knew that his lightning bolt wouldn't even
tickle me.
But if you're happy getting the same number of targets as you likely would be able to with a fireball, you should never hit yoru friends. For a bit of risk and/or extra brainpower, you could probably get another 1-3 foes per bolt, when in close quarters.

This line you speak of can be easily broken up, if I am interpreting it correctly, by just flanking the party.
You assume either fighter incompetence, and/or overwhelming numbers. Neither assumption should be held as sufficiently universal to devalue lightning bolt.

Its easy to get two people, but much much harder to get three. Where as with fireball, unless they split up very far apart, its much easier to get two, three, even fifteen.
Fifteen? Bull. Absolute and total
bull. And getting more with a Fireball requires you to get some or
all of your allies, too. Fireball isn't selective!
Moleculo said:
So I guess what I am saying is the difficulty to get more than one person grows more quickly (I am avoiding big-O notation at all costs damn you to hell CompSci) with Lightning Bolt. And in your case, it is still a lot easier to use fireball than lightning bolt.
Riiiiiight ... fireball right on yoru own line of fighters, sure, that'll work, and not toast your own allies. Suuuuure ...
Feh.
