A 19-year-old man and a 16-year-old girl died during the crash in Oldbury at around 11.30pm on Sunday when a blue Nissan Skyline crashed off the road.
As well as the two teenage victims a man and woman in their 20s are fighting for their life in hospital. A 54-year-old man was arrested on suspicion of causing death by dangerous driving and remains in police custody.
The tragedy was believed to have happened during a late-night car meet.
Mohammed Khan, aged 44, who lives off Oldbury Road told the Express & Star: "There was lots of people standing around on a Sunday night which seemed strange.
"We heard a massive bang, and when we looked up the road saw people running all over the place and screaming. It is such a shame two young people have died."
Mr Khan said he and others have complained about the road "for years", adding: "I do not allow my children out on their own at anytime of the day.
"There will now be a type of shrine built to victims on the road which I will have to pass every day with my children and have to explain why people died so near their home."
He also called for speed bumps or other traffic calming measures to be installed.
West Midlands Police closed off the road for nine hours from Sunday night to Monday morning as crash investigation officers combed the area for clues about the crash.
Detective Sergeant Paul Hughes, from the force's Serious Collision Investigation Unit, said: "This is a tragic incident and our thoughts remain with all the families affected. We have specialist family liaison officers supporting them at this terrible time.
"We know that there were lots of people who had gathered in the area at the time of the collision and would have witnessed what happened. I would urge those people to get in touch if they haven’t already done so."
He also urged people not to share and photos or video from the incident on social media.
“I would ask people not to share videos or photos on social media. If you have anything that could help with our investigation, then please get in touch," he continued.
"This is very distressing for the families affected and it’s not appropriate for them to see things that could upset them on social media.
"I want to thank everyone who has provided a statement so far, and ask anyone else with dashcam footage or any other witnesses to contact us."
West Midlands Ambulance Service sent three ambulances, two paramedic officers, a MERIT trauma doctor and critical care paramedic, and a BASICS emergency doctor to the scene where they found five patients. A spokeswoman said crews arrived to find five patients.

“They received advanced trauma care from ambulance staff at the scene and en route to Queen Elizabeth Hospital.

The tragedy in Oldbury followed on from the death of an 18-year-old in Birmingham when a car crashed into a tree in Hall Green. Two others were left with serious injuries.
Named online as Chad Heath the 18-year-old was the passenger of the Kia Stonic that hit a tree at the junction of Solihull Lane and Pitmaston Road just before midnight on Saturday.
Chad’s brother Adam Heath posted an emotional post on Facebook about the tragedy.
He said: “I am in pieces right now. Chad was 18 and had his whole life ahead of him. He was the nicest and kindest kid brother ever, I’d trust him with my life, seeing him lying there lifeless I would have swapped places if I could.”
The broken-hearted brother revealed Chad was not wearing a seatbelt when the car crashed into the tree.
He said: “If he was wearing a seatbelt when the car crashed into the tree then he might have stood a chance. Anyone reading this please don’t gamble with your life and just click the seatbelt and save your family being devastated.”
A spokeswoman from West Midlands Ambulance Service said: “We were called at 11.59pm on Saturday to a collision involving one car at the junction of Solihull Lane and Pitmaston Road in Hall Green.
