This is stupid. Everyone can see a car long before they hear it. If you get hit by a car because you didn't look, that is your fault. The exceptions are the blind. However, generally speaking it will take someone longer to cross a street than it will take a car to go from being beyond hearing distance to you. And that goes for most cars. Plus, every car has a horn. If audible warning is required, the driver can honk.
Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
