“oomis: Then leave it to whose job it is to make these decisions — Rabbonim & Poskim. If THEY decide its a tznius issue, you and I are nothings and can say nothing regarding THEIR decision for their kehilos. (If you are of a different kehila, simply follow your Rabbonim and let them follow theirs.) “
I am sorry,but I do not agree with you that this is a rabbinical issue whatsoever. Your rabbonim and poskim (not mine) who say it is assur, may have a very different mindset than most others. No one is supposed to asser something that imposes a hardship on most of the klal, and will sure to not be followed by the rohv am (I am not talking about mamesh halacha from the Torah, but rather areas that are shades of gray). Women (hello!) comprise more than a majority of klal Yisroel. When women had other modes of transportation, they used them. Supposing a woman is unmarried, widowed, divorced, etc. Should she have to wait for someone to drive her around? SHould she have to take cabs (very expensive on a regular basis) and public transport late at night, rather than the safety of her own car? In olden times, are you telling me frum women never drove a wagon or rode on a horse or donkey? NEVER?????? I do not believe that. And neither do most people. AS I Said earlier, our Emahos CLEARLY did. A horse is less tzniusdig for a woman to sit on, then a car. I won’t even ride a bicycle, even in a very long skirt, as I have seen many frum women do, because it is a potentially untzniusdig view from the back.
