Hi asroc, the reason not to use bleach on the garden is the same reason it was effective on your drive - it kills everything and doesn't discriminate between weeds, plants or the good organisms living in your soil.
There isn't a failsafe solution to mares tail I'm afraid, especially if its coming through from a neighbours garden. If it is the shared area that is infested maybe it would be worth your while asking them if you can treat the whole area. Posters on here have successfully used standard glysophate weedkiller but you do need to bruise the stems before applying so that is absorbed and you will need repeated applications before it's conquered.
i just accept that it's in my garden and pull it up when doing a usual weeding session. Repeated weeding is supposed to weaken it over time.
