I actually did have a car with a Nigerian, reverse into me at a junction. He was sitting there crunching away at the gears, then proceeded to chuck it in reverse and banged it into me.
Before anything, I jumped out and yelled over to a cyclist who was near by so he would be a witness, otherwise i know it would have been my word against his.. The Nigerian then proceeded to try and blame me saying I didn't have my lights on!!!!!!!!!!!!!! My cars lights at the time turned off when you took the keys out of the ignition. Since I pulled the keys when i got out. Luckily for me i maintained my temper and didn't launch a salvo of punches in his face for blatantly trying to pass the blame back on me, but all during this, i failed to actually look at the car which was pretty much fine.. So we all went about our business.
Then about three yrs ago, i had the same happen again. This time in the USA. A van decided to reverse into me, once again at a set of lights, with me sitting behind, and because it had a tow bar it actually punctured a hole right in the middle of my bumper. Once again i went for a witness, a hispanic woman who my guess was probably illegal since she gave me a false tel number. FORTUNATELY, the guy was legit, and said he'll admit to it all, which he did and his boss paid out cash to the repair shop for a new bumper and respray.
The worst part is to cover my own butt, i called my insurance company, who now have it on record that i was involved in an accident. Even though i could have entirely bypassed the insurance, since the van driver was decent enough to just directly pay the repair shop.. At the time, i thought he could be sneaky and say it was me that went into him though, so i made the call.
