So true. My son is an avid cyclists, often riding 100 miles a week on the road. Before he was 21 he had been involved in two car/bicycle accidents that were not his fault. Both resulted in an ambulance ride. The second resulted in broken bones and severe concussion. He was lucky as the other cyclist, two feet to his right, was permanently disabled with a brain shearing injury. The two of them totalled a late model Ford Explorer when the 16 YO driver turned left in front of them in daylight. I believe a flashing strobe may have helped, but neither rider had one.
Bicycle riders have rights but don't get the respect moto riders do. They get pushed off the road or out into the dirty shoulder. They get tow mirrors flying by their heads and they get car doors opened in front of them. Most often, they are wear not much more than underwear and a foam helmet.
I've never seen a pool noodle but its not a bad idea and should be fully legal here in CA. Drivers often don't give cyclists the legal room or just don't know how wide their vehicle is. If you ride then road on a bicycle, you know as it has happened to you. I think drivers should be ticketed for passing bicyclists too closely as it is illegal. Unfortunately I've never heard of it happening.
Be safe out there people.
