Even if the vehicle code has been amended, stopping for people at a crosswalk is a common courtesy. It is true that pedestrians should also watch for other cars, but this just common sense.

A dangerous thing I have noticed is the tendency of stopped drivers to sometimes wave people to go ahead. This is coupled with a tendency of pedestrians to often jump to do whatever is suggested to them before they check what other cars are doing. I'd suggest stopped drivers not signal pedestrians, and pedestrians make sure all cars are stopped no matter what is signaled. This seems like common sense, but I mention it because it is something I've repeatedly seen.
