After all these years, auto audio warning technology is limited to no seat belt warning. It is time to expand into other critical areas.
One critical area is to warn of in-coming traffic before opening the car door to exit.
Another critical area is to warn to lock your car if your car is stationary- to prevent burglar break in. Most cars do auto lock only if car has moved certain distance.
Dear car manufacturers, please do work on these. Or you can build and give us a r2d2 or bb8 instead. Thank you.
