The average vehicle can hold 4 people. This would be the space required to move 48 people who are all going to different places, but lots of people car pool, and I know I'm taking the word "required" too literally here, but this image should look like this.
I completely agree with the notion that riding your bike to work is environmentally friendly, of course!
"In the US, car occupancy, is near of 1.7 people per car, (against around 1.5 occupant(s) by car in EU)."
Let's say there are roughly 67 people on that image, they would use 40 #cars in the US and 45 cars in the EU.
Not 12 like you drew in your picture...
I don't think that saying how many passengers could these cars move isn't helpful at all.
Then "required" is *definitely* not needed in this meme, since it is talking about averages.
I make the same kind of mistakes with my English, because English sucks, but thanks for the clarification. I understand it better now!
