On Shabbat / Yom Tov when walking slowly except going to Shul or to perform a mitzvah etc. what about crossing the street and the cars are impatient, is it allowed to walk faster for that?
ב"ה Shalom From, the point of running on Shabbat, Achronim have allowed to run on Shabbat in a case of discomfort. For example, a person can walk quicker somewhere to avoid a dog, or a person may run to get out of the rain. (See פסקי תשובות סי' שא:). Similarly, when you feel discomfort due to an impatient driver which causes discomfort you should be allowed to walk quicker. However, one may raise an issue, that if the driver is Jewish, then perhaps the running induces the driver to step on the gas pedal which is a severe Chilul Shabbat= desecration of Shabbat. However, Rav Moshe Feinstein zt"l wrote , (אגרות משה יורה דעה חלק ג סי' צ) that when a person is doing a permitted act and minding his own business, he does not have to take into account the actions of others who are committing an Aveira, since they are doing it on their own volition. I saw the same idea by Rav Ya'acov Ariel shlit"a. Therefore, you may hasten your pace while crossing the street even on Shabbat, if you feel discomfort because of the impatient waiting driver and it is not considered that because you walked quicker you caused the driver to drive on Shabbat. However, you should not motion to the driver to slow down or to go ahead. All the Best Gmar Chatimah Tova.
