As to the member who asked when does a right of way stop being a right of way... Simple answer is when it can cost you your life. When I was a copper we had a saying well that rider/driver was dead right. he had the right of way. but now he is just as dead as he was right. I ALWAYS assume a vehicle is going to invade my lane/area.
" Here lies the body of George O'Day.
He died maintaining his right of way.
He was right, dead right as he rode along,
But he is just as dead as if he were wrong."
I haven't been riding long, but even in my car I just treat it like no one should have a license. Don't assume right of way, don't assume people can see you, be prepared for the worst case scenario in every situation.
Unfortunately with the amount of incapable drivers/riders, I believe this is the only way to survive. No matter your means of transportation. At the end of the day its your own responsibility to keep yourself safe. There are no accidents on the roads, just a series of miscalculations that can turn catastrophic. (Sometimes 1 or the other driver, sometimes both) do your best to anticipate others mistakes.
Assuming the reports are true both the driver and rider in this situation miscalculated something. Which unfortunately led to the passing of these 2 young people.
To the Mom. I'm very sorry for your loss. I wouldn't wish a parent loosing their child for any reason on anyone.
