The net says a 2020 Vette brakes from 60 in 110'. From 170 in 800'. Say he needed 700', and your reaction time of 1.5, more likely 2.5 because of his blood alcohol. By the time he recognized what was about to happen and he comes to a dead stop, that's like a quarter mile.
Maybe he needs much less to get to 90 and swerve to avoid, IDK
