Non commercial Class B license Calif

I took the Calif Class B test a few months ago and I was not required to parallel park. Pulling forward and backing through some cones, doing the 90 degree dock manuver, and some street testing. Although your not tested on it, we spent a good deal of time discussing the air brakes. After going through the process I feel a lot better about driving the rig. I learned a lot of good info preparing for the exam, especially the air brakes. I understand the resistance of many to the test but I wonder at what level you think testing should be implemented? How big of vehicle should you be allowed to drive without any special license? We all make fun of people trying to park their rig but at the same time don't think is necessary to see if they are even qualified to drive them. Calif is pretty lenient in their requirements, a special license is required for only those rigs over 40 ft. There are some states that require one on anything over 26K. I don't mind the testing, in my experience people think they are better at something than they really are, especially when it comes to driving.
