Co v této větě prosím znamená “mind you”? Mind you, that crossroads is dangerous. I've seen some near misses there before now. I think they should put traffic lights there. It says here that they had put up warning signs only a week before the accident, but that obviously wasn't enough. A v té posledné větě je present perfect, protože pověsili to výstražné značení v době před tou nehodou?
