COVID derails Musk's plan to shuttle CES attendees in underground Teslas Two tunnels are ready, but the pandemic has stopped the Loop in its tracks. Image: LVCVA 2021-01-11 11:00:00 UTC If CES 2021 were taking place in Las Vegas as usual, Elon Musk's underground loop tunnels would've been up and running to whisk conference attendees underground from one convention hall to the other. Instead, the Musk-owned Boring Company's Las Vegas Convention Center Loop is fully excavated beneath the massive convention buildings, but is not yet operational. With COVID-19 restrictions forcing a virtual CES this year, no one is traveling above ground, let alone below it.Â
