What does it matter? We can play Monday morning quarterback all we want, but the fact remains, one person is dead for clipping another car while trying to make a lane change.
What can we learn for this?
A lot!
Obey the speed limit.
Use your turn signals!
Slow down in congested areas.
Let people merge no matter how stupid they may be.
Drive defensively!!
Keep an eye on the road at all times and at least 5-7 cars ahead of you and to your left and right!
Take a look at the photos of the cars involved, including the red mustang.
Perhaps a last minute lane change, clipped the Mustang and had no chance against the truck!
