The 24-year-old suspect was flooring his white luxury vehicle down Henry street in Carroll Gardens — just steps away from an NYPD stationhouse — when he missed a detective by inches and slammed into the other car, police said. The other vehicle, a black Audi, was pushed up the curb and sent flying into a corner deli, shattering its windows, according to surveillance footage obtained by The Post. EMTs transported the Audi driver and a young woman in a passenger seat in the Mercedes to the hospital in stable condition. There were no other injuries.
