I think this is a fantastic idea and a great mod. Thank you!!!

This proves that you're much better at creating your kind of world than I am with mine. Great work!

Thanks! This is great

Will this only happen for cars in Al-Simhara or in regular worlds also? Will my sims in Bridgeport still drive around with Egyptian plates?

This mod will affect all cars covered by the mod for any world. Bridgeport Sims will have these Egyptian plates, so it's really best to only have in your folder if you plan on playing in an Egyptian world. If this is bothersome, I suggest taking this out of your folder when you play non-Egyptian worlds. You can, obviously, put it back in if you plan to play an Egyptian world. Sometimes I wish TS3 had some sort of hotloader where you could rescan your downloads in real time so you wouldn't have to quit the game to change out CC, but I digress.
