The closest calls that I've had is from gawkers trying to catch up to me for a closer look. Almost got rear-ended at night because of this. I have also created two rear-enders from rubber neckers that rubber-necked a tad too long...oops!
I can chuckle about it because both were low speed bumper benders and nothing more.
Someone once told me (on this forum) that a Cobra is like a custom Harley, but on four wheels instead of two...you have to be alert all the time for people around you. Truer words were never spoken.
