(i think i may have seen it happen) calm down!.nowadays the bulbs in your lights can be checked to see if they were on at the time. (this is usually done in serious accidents on mways to see if the car in front had its brakes on before being hit) so this persons reverse lights shouldve been on? it may cost a bit to get them checked,if at all you can? but if your cars written off it may be worth a try.
