What improvements do you see in daily life that could make life easier for everyone?

I was out shopping with my mom this weekend. She has difficulty walking and uses handicap parking spaces to make it easier to get into stores. We drove to two different stores and parked in a handicap space each time. Both stores had design issues with the placement of the handicap spaces and landscape beds. Good design would have prevented this scenario and made life easier for all those using the parking space. What design issues have you seen that could improve life for everyone?
