In my area -
A buddy of mine sometimes rides with a ~70 YO guy who has a Goldwing trike.
He's told me that the guy was recently riding alone (lady on behind him), and was third in a line of three vehicles on the road: truck, bike, trike.
They all top a hill, one after the other, of course, to come upon someone in a SUV, stopped in the road, waiting to turn.
Truck goes off road on one side of SUV. Bike goes to the other side, leaving the trike with nowhere to go (as I was told).
Trike rear ends SUV, I suppose. Rider breaks wrist. Trike's passenger breaks both ankles. Surgery for both.
Story as it was relayed to me.
(Reminder) lesson for me? Don't follow too closely / don't out-ride your range of vision.
Please be careful out there.
