Lets assume we disqualify the cars going left ro right, and if we also assume each car only has 1 person per car, that means the cars is 32.
A bus that size is usually built to fit around 50ish people using every seat, but none standing.
I ride my local bus everyday. It's NEVER full like that. I might have 6 people on the bus. Sometimes I'm the only rider.
So, yeah, a bus CAN hold roughly as many prople as cars, (again assuming only 1 person per car, which probably isn't the case 100%), the reality is that's not functionally true.
