halacha - Will rabbis allow brainy Shabbat driving?


Saw this news story a few days ago about a car being driven with just thought, using a special cap with sensors.

To me this still seems entirely muktzeh and therefor should be no question about it's permissibility on Sabbath or not.


By virtue of a Rabbinic discussion it would appear that there is a possibility that this might be acceptable. What are the issues that would allow this?



Answer



Such a thing won't be allowed in practice, but on what level will it be forbidden? Any action is caused by the brain, but it has to result in a physical action to be an actual melacha. Even grama, etc. have a primary physical action involved. So its unlikely thinking can be a melacha d'oraysa. The question is what if you kill someone by thinking?
