I think (hope) i understand what you are trying to say and achieve but as a motorist myself i seldom see how you can 'deter' motorists away from you. We share the roads with each other, i dare say unfortunately so but no one mode of transport owns the road... Country roads by definition are twisty, narrow and have limited visibility owing to poorly maintained hedgerows and trees. Cars will swing around blind corners at national speed limits and will sometimes slam the anchors on when they see a cyclist right there. How do you prepare for that? Tow a beacon? Honestly, other than making yourself as visible as possible i see no other way. Those long flag poles you often see on recumbent trikes are not a bad idea, hopefully they'll be seen over the hedges. Also bare in mind, pedestrians and joggers use country lanes often with no pavement. Its the way of our networks unfortunately.Can you please let me know any ways to deter motorists in the countryside when riding?
Sounds overly complicated. I once rode a few miles with a boat hook balanced on my handlebars couched like a jousting lance (long story).Slightly seriously a 3rd wheel which when fastened to the bike is 1.5M from the frame with a pole on it with flashing red LED's to the rear & white/amber to the front. It should be made of as lightweight material as possible (carbon fibre) & if it is hit it should detach from the bicycle so as to protect the rider. But it should also be capable of being moved 90 degrees from alongside the cycle to being trailed behind the cycle for when you are on cycle paths or narrow situations.
