I reckon religon ought to move with the times a bit.
I'm no expert on this exact travel to synagogue by feet only thing [and there is a similar rule in Islam ie you should walk to the mosque], but I was told that the original rule was brought in to give animals a rest, ie , thousands of years ago folk would ride everywhere on donkeys horses etc every day, nowadays we have cars, buses, bikes, motobikes etc, none of these things existed when the rules where made up.

Also other stuff, like in Islam all alcohol is banned, but recent medical research has proven that a little bit of alcohol is better than none at all, ie 1 pint or 1 glass of wine a day.

And them lot waht won't have blood transfusions, ie in the olden days drinking blood was stupid, as there were no fridges, and you would get ill.
And when blood transfusions was first invented, they didn't know about blood groups etc, so people died, but nowadays its all put in groups and tested, and heated up to kill germs etc.

If I was in charge of religon, i would relax the rules a bit.
