Peter, I feel for you. I wouldn't be surprised if it wasn't some sort of game being played on you. I also wouldn't be surprised of the two rides had elevated BAC's. Motorcycles and more than a few of their drivers scare the shit out of me. I hate HD's that hug the center line or, like you mentioned, ride two abreast in a lane. I've had more than a few pass in absolutely unsafe situations and it infuriates be. I seldom see motorcyclists exercising anything remotely resembling road ediquette. Why, take is so personally?
My Range Rover took the leg off a motorcyclist once. Severed it right below the knee. Blood was gushing like a fountain from his femural artery. He was on a '78 HD Lowrider, looked away, swerved into my lane and hit me right on the left headlight. He ultimately survived thanks to a paramedic who lived in right where this accident took place. She was able to stop/slow the bleeding until the ambulance arrived. It turned out his BAC was above .30. Thankfully, I was ok.
That accident occurred back in '94.
Less than a half mile from the scene, in '89 I had the same thing happen with the exception that I was travelling in the opposite direction. A '79 HD FLH, fully dressed, crossed over the double yellow and slammed into my '88 Pathfinder at my left headlight. The motorcyclist was not wearing a helmet, was tossed into my windshield and slid off onto the ground. My front wheel was completely destroyed and I swerved into the oncoming traffic. I hit and turned sideways the car following the motorcycle. That car was filled with the motorcyclist's friends. Rather than attend to their friend they spend the initial minutes after impact hiding all the beer, whisky and cocaine they were travelling with. Yup, the motorcyclist had a BAC of .26. He survived, minus a leg. I had minor injuries but was forced to go through years of litigatory hell. Ambulance chasers served me with an intent to sue with days of the accident. In the end they got nothing.
They have a joke about the town I live in here in CT. New Milford, lots of winding roads and lots of bars. Every weekend the area is flooded with motorcyclists from all over the region. There used to have an enormous biker jamboree a few miles to the south in Danbury. It took place in spring and fall. In fact, my accident that occurred in '94 was on the day of the spring jamboree and my motorcyclist was just extending the celebration shortly before running into my truck.
Sorry all you motorcyclists but I will never feel safe again about your presence on the road. I cringe when I see a motorcycle heading towards me hugging the center line. When somebody on a rice rocket illegally passes me and blows off at 100 mph I hang back waiting in anticipation of sirens and an accident scene. It's an all too common occurrence here in NW CT and alcohol plays way too large a role in these accidents.
