In Australia ownership of a land plot extends to the centre of the earth. Owners are awarded compensation for boring under their plot as well as a separate compensation for noise and vibration while working in the vicinity underneath. I wonder what the situation is in Israel?

I think these projects are going to be a huge economic boost for Tel Aviv as it will ease the commutes of so many workers. However, based on the maps I've seen on the NTA web site, it doesn't seem like this system is really meant to facilitate getting around Tel Aviv itself. I think the Red Line only stops at Carlebach and Allenby. Does the transportation master plan for Tel Aviv including keeping the little Sherut minibuses and the existing bus system?

Why import foreign workers who send abroad their salaries instead of paying Israelis who will spend in Israel?
