It still comes down to simple user error, not so much the vehicle. But, I won't disturb the anti truck circlejerk.

That's called failure to check your blind spot. I've driven a pickup for over a decade and never not been able to see when a vehicle is next to me if I physically turn and check my blind spot. Though we are promoting people becoming more lazy with this as most new cars just do this for you. In my newer work vehicle, the side mirrors have an orange indicator turn on when someone's hanging in your blind spot.
