Founder of SpaceX, Tesla and Neuralink Elon Musk is in negotiations with Israel’s government to build tunnels in the Jewish state, said Israeli Prime Minister Benjamin Netanyahu this week.

“I met a man that they call Elon Musk—have you heard of him? A real genius,” said Netanyahu at a campaign event on Tuesday when asked about Israel’s transportation infrastructure. “Right now, we’re in conversation with him to see if we can tunnel the State of Israel.”

Netanyahu said he and Musk ate breakfast at the prime minister’s residence, where the billionaire entrepreneur mentioned tunneling.

Musk’s Boring Co. tunneling firm could improve development in Israel’s transportation network, which is beset by one of the developed world’s most congested traffic patterns.

Ineffective public transportation could cost the economy $6.9 billion annually by 2030 if dire changes aren’t done, according to the state comptroller.
