bpt-
Please be mochel me the vocab nitpick, but:
1) The expression is “toe the line”, and it means to do exactly what one is supposed to do without deviating even minimally. What you are describing is more like “pushing the envelope” or “testing the limits”. “Toe” vs. “tow” is a common error.
2) I think you mean “flouting” the rules, not “flaunting” the rules. This is an even more common error, which I’ve seen in newspapers.
3) As someone who’s made many errors myself (e.g. “casting aspirations” instead of “casting aspersions”, among others), I’m certainly not criticizing from an ivory tower of impeccable English, but the title of this thread caught my eye.
