At some point, they become a bit 'psytrance music video', from what I remember.
I can’t imagine this being safe at all in a city, with the amount of underground infrastructure and weight of buildings, houses, sidewalks and pavement all around you. Seems irresponsible.
I'm surprised that no-one located (somehow) and reported him before then.
I'm sure the digger would say that it's just rubble (nothing structural) he was touching, but there are of course plenty of issues & it's besides the point / could be incorrect anyway.
