You're driving and see a billboard or basically any urban development signage with a message you can't understand... where you don't even know what the product is... don't you want to swerve off the road and chop it down. It's a waste of space, resources and time.

You go by that new retail store, YOU CAN'T READ the contact details because the print is too small... don't you want to stop and give a marketing lecture?

After all you're driving 50 kilometers an hour! How do they expect you to read that??
