NOTWITHSTANDING ANY OTHER LAW, A PEACE OFFICER MAY LAWFULLY STOP
ANY PERSON WHO IS OPERATING A MOTOR VEHICLE IF THE OFFICER HAS REASONABLE
SUSPICION TO BELIEVE THE PERSON IS IN VIOLATION OF ANY CIVIL TRAFFIC LAW AND
THIS SECTION.
------------Let's look at an example of that according to the bill:
IT IS UNLAWFUL FOR A PERSON TO ENTER A MOTOR VEHICLE THAT IS
STOPPED ON A STREET, ROADWAY OR HIGHWAY IN ORDER TO BE HIRED BY AN OCCUPANT
OF THE MOTOR VEHICLE AND TO BE TRANSPORTED TO WORK AT A DIFFERENT LOCATION IF
THE MOTOR VEHICLE BLOCKS OR IMPEDES THE NORMAL MOVEMENT OF TRAFFIC.
-------------------That means if you get into a ******* cab, you could be stopped and arrested. How many have gotten into a cab in the middle of the street? Oh, everyone?
