im with 333,i drive all day,i do it a bit different on the bike as im more at risk,i sometimes flash my beams behind a car who i can see is on the phone to wake them up that im there,i dont use my phone while driving full stop!i think theres a thread on this "everyone is out to squash you"stuff ,and its all true,stay alert,the car full of youngsters in front will swerve into a burger place with no indicators across two lanes taking you out,the people moving house with the insecure load will lose an article in front of you taking you out,the busy courier van dosent give a damn and will take you out,cruising along beside a semi is taking yourself out,i think bright lights in a heavy city traffic situation is better than on the open road,the city has a lot of zig zag traffic where as the open road is head to head mostly.,if you turn your light off then back on it grabs more attention,i do that from time to time.the driver might think "why did he do that to me?"the answer is i did it to everyone.and you noticed me now.
