I approach intersections as-though something stupid might happen, and often will begin to alert the car behind me by hitting the brake light repeatedly as I approach the intersection. f I notice the car behind me wants to tailgate, I just slow-down, or look to pull to the right, not in the intersection.
I have had one accident involving a left-turner, on my way home from fire-rescue, on an eight-lane highway in N Miami Beach about 3 blocks from where I brought patients and taught American Heart Assoc. classes like ACLS/PALS, and BLS. She turned left and stopped across my lane, in-front of four lanes of traffic coming from the opposite way. There was no-place to go, except to the hospital after I got-up off the pavement and had Miami-Dade Fire Rescue transport me. I was lucky, I had lots of bruises, a broken foot, a concussion, and a guardian angel keeping me from the Grim Reaper.
A Good Samaritan directly-behind me in traffic followed the ambulance to the hospital and waited to speak to me, he gave a report to Miami-Dade Co. Police about the accident. He said that when he saw me highside into the glass canopy of the Honda sedan I hit, after I tried to violently brake to avoid the impact, he thought he just witnessed a roadway fatality. "Then," he said, "you got-up off the pavement where you landed after the impact, and began screaming at the driver, with your helmet still-on!" I don't recall that. My helmet hit the "A" pillar and cracked her windshield, and as I was doing a "Superman" along-side her windows, my foot broke her rear window. It must have been a sight to see.
My co-worker from fire-rescue came to the hospital to pick me up. He was in a brand-new Dodge 1/2 ton p-u, and I got nauseated on the ride home, rolled-down the window, and puked all down the side of the truck as he tried to get to the swale to let me out.
I was out of work 2.5 months recuperating. No lasting effects, thank-God!
