Buses letting people on by back door?

I’m on a 55 bus in which the driver has taped off the front door section & is only letting passengers board via the back. Anyone else see this today?

Also was thinking: this is the first time I’m encountering a crisis my parents did not. I had older parents and whatever happened they could always counter it with “the Depression… the war…”. But they never had a “pandemic” card to play.
