The wise thing to do is escape the situation with very minimal fine, u know the system is corrupt and yes u can try to change it ..and with a cost. talk to them nicely in a manner u can convince them, if they ask for 100/- check the situation and act accordingly,.. if they they are strict then u'll come to know immediately and surely they find something wrong in ur bike, some are casual .. just pay less to them and escape
and +1 to highway thing
