"Roadblock" (tentative) is a cutscene in Resident Evil Outbreak.
Dorian drives the survivors through back roads, avoiding the chaos of the main roads. After a short while, he reaches a roadblock that he cannot pass. He apologizes and tells the survivors they will have to walk the rest of the way. Outraged, the survivors do just that.
Dorian: "The highway is too dangerous... we're taking side streets."
"...Damn, another barricade."
"As you can see, there are too many road blocks."
"I'm afraid you'll have to get out and continue on foot."
Dorian: The main roads are too dangerous... We'll have to go through the back streets. Here too? Dammit... Every path is completely blocked, as you can see. There's no choice left but to walk... I'm sorry, but I have to ask you to get out.
