Is that a serious question?
You're not responsible for them... you ARE responsible for yourself.
If you find it difficult to be fully aware of your surroundings and find yourself crossing driveways without looking over your shoulder... then the blame lies with you... just as it would a driver.
I drive, I walk, I ride my bicycle... I'm responsible for being aware of others and not crossing a driveway when there's a risk of colliding with something or someone.
Are you?

I see you are too heavily invested in the myth of individual responsibility for collective problems for further discussion to be productive.
