A design award has been given for a concept that would allow existing traffic lights to be retrofitted with progress bars that offer a visual representation of when the light will change. Several benefits have been suggested…
- Less pollution, as drivers can turn their engines off and cut carbon emissions while waiting for the green light,
- Less fuel consumption, as turning off vehicle engines lowers fuel consumption in the long run,
- Less stress, since drivers know exactly how long to wait, and
- Safer driving, as all traffic participants are fully aware of how much time they have left before the light changes, reducing the chance for potential traffic accidents.

Ford is developing a seat belt that inflates when the car detects a crash. In The Wall Street Journal, Matthew Dolan writes:
Its inflatable rear seat belts spread crash forces over five times more area of the body than conventional seat belts, said Sue Cischke, Ford group vice president of sustainability, environmental and safety engineering
Each belt’s tubular air bag inflates with cold compressed gas, which flows through a specially designed buckle from a cylinder housed below the seat. The inflatable belt’s accordion-folded bag breaks through the belt fabric as it fills with gas, expanding sideways across the occupant’s body. It looks something like a water wing children wear in the pool before they know how to swim.
