I totally agree. Even Superheroes need to be safe when crossing! Well, not unless the superhero who has wing or cape. :p
I agree every human being needs to be safe when they are crossing or else there are just trying to take a risk. So remember always check for cars before you cross the road
I like the way Justice League used superhero blockheadz instead of humans and Hulk and Captain America died except for Iron Man and you let out the message to people in a fun way
I think that Hulk might be too heavy for the cars.
I agree with Anthony and why can't Iron man fly over.
