Although I understand the numbers and know how probability works, like you I'm still concerned so I installed a pair of Whelen TIR3 flashing strobes and wired them to my rear brake lamp. They WILL get anyone's attention that is behind me, day or night. They have a variety of really annoying/attention getting patterns to select from and I've set mine up to will wig-wig for three cycles, go solid and then wig-wag for three more cycles, repeating for as long as I'm on the brakes.
Maybe the $125 or so will put your mind at ease and if not, just remember that the odds are (relatively) slim you'll get hit from behind.
