It all went down in Miami on Saturday ... Rodriguez and his family were just on a regular outing in their black Chevy Suburban when the stolen cop car plowed into them and exploded into flames.
The suspect had allegedly stolen the car from a nearby restaurant after distracting the officers -- and was speeding off when he crashed into Rodriguez. The suspect was killed in the crash.
Rodriguez appeared okay -- his wife and 2 children (8-years-old and 2-years-old) were hospitalized.
