Left church and down to a little country "T" intersection. Guy in front of me stops at the stop sign, my buddy and his son are starting the left turn from the "T" part of the intersection to head to church for second service and as they're about at the 45 degree point the guy in front of me starts moving forward and left...I'm in the car yelling "don't do it....stop, stop stop" but he continues out and makes contact with the end of the front cowling then my buddy's leg/ankle and proceeds to push the bike over tossing both of them off...car's speed was maybe 3-4 MPH. Bike was maybe 5-8 mph.... result...broken left ankle for my buddy, cuts and such on his leg, his son has a few bruises, left bag departed the bike (Connie 1400) and ended up 30' from the intersection...how I have no idea....and rash on the bike. The gear he wears is a hi-viz jacket, helmet, gloves, dress pants and sneakers. Would a set of good boots have kept his ankle from breaking? Dunno..... weird thing to watch. Driver said he never saw them. Very difficult to comprehend how you can miss a bike right in front of you...4' away with a guy wearing hi-viz, but he sure didn't hit them on purpose. Be vigilant and keep repeating to yourself...."I am invisible.....I am invisible"
