Bad decision
As she was driving, she decided to go back onto the highway and take the usual route she would take on her way home. This was probably the worst decision that she could have made but take into account that she was definitely not in the right state of mind at the time.
Emma went off the road and onto the 405 interstate highway, a main traffic artery for people who live in the Los Angeles area. It wasn’t rush hour, so this meant that there was more space for cars to do higher speeds, meaning more dangerous encounters were about to take place.
