This method may cause unwanted others noticing you. Most importantly, Do not get overboard with the tapping of brake lights and dome lights. DO NOT!: Expose your self to a trucker or anyone for that matter. This is a very RISKY way to cruise and as stated above. Keep in mind that there is just as many men or ( truckers ) out there that will bust you as there is that want to meet up with you. Due to this scenario you need to ( PROPERLY ) cruise and not bother others that are not cruising or looking for the same thing your looking for.
There is also many other methods of cruising, Some less risky and others more risky. Most importantly, If you go out there and cruise.
