I prefer index variable names that are two words. The second word is always 'index' and the first word describes the enumerable objects. carIndex, productIndex, thingIndex
I'm not paid by the character count. Longer and more descriptive is better. Long lines that go past your 1080p monitor are probably not long because of variable names but because you insist on doing many things in one line (quit doin' that). For small functions this isn't necessary, but too often I'm shunted to the middle of a big function with two or three indecies doing acrobatics over one another and while working on it I have to constantly remind myself that this i and j mean particular things.
I have had too many times where I have been confused trying to figure out a giant nested loop because the writer used i/j/k or x/y/z. It’s even worse when they confused when a particular bug is because they confused what their single letter variables were and used j somewhere instead of i and no one caught it because it is so easy to brush over. Name your stuff what it is, make your life easier, make others lives easier.
If you need three iterators, it's time for at least one function encapsulating that inner loop.
