I despise being tailgated! Some nights I'll be toodling to work at 55-60 mph, and some jerk will come up against my damn bumper, blinding me with their headlights as well as scaring me. I've often wondered if they would do that if they knew that the person they were terrorizing could be the nurse/doctor/deputy who later will be working to save their loved one's life with shaky hands and a raging headache.
Anyway, this guy or gal gets his dose of karma. I'm glad he didn't careen into traffic. I was a bit amazed at the cars that zipped on by without stopping to render aid, but I will give them the benefit of the doubt and assume that they called for help.
