1. At many places they have introduced a 3 bin system for trash: a trash bin, compost bin, and recycle bin. Most people broadly understand what can go in each bin but after eating a meal there will always be one or two items that they have no clue about. What happens when we make a mistake? When people throw non-recyclable items in recycle bins what happens?
2. Why have airplanes not gotten faster? Have we already reached the speed where going faster will increase the chances of casualties? (This is the argument for cars.) Imagine being able to fly from California to New York in 2 hours. The ability to do any flight in Continental US without a stopover. International flights without dreading the long flight.
3. One of the hardest things to figure out is arm rest etiquette on any type of public transportation. If the arm rest is shared who is supposed to get it and what is the appropriate amount of physical contact once someone has claimed it?
4. Drinking fountains are usually placed close together with one short and one tall fountain. But the problem with these fountains is that they are close enough to each other that most adults will not use either fountain if the other one is being used. When installing new fountains either only put in a single fountain or space the fountains far enough so that two people can use them comfortably.
5. I hate buying tickets on TicketMaster. I think I am buying a $50 ticket but as soon as I confirm that I am a human they let me know that I need to pay an additional $20 convenience fee. The worse part is they often have an option where the shipping charge for standard mail costs money while printing the ticket is free. Someone needs to break the monopoly.
