My car was totaled in an accident

My Honda Accord was totaled in a car accident. It was rear-ended by a silver Suzuki while I was driving to work.
The funny thing is that we didn’t call police but they appeared in about 5 minutes after the accident happened. Without even getting out of his car, the police officer said we must leave the freeway as soon as possible and exchange our insurance information somewhere else. And… he drove away!
I didn’t want to cause trouble to all those people stuck in morning traffic because of our accident and offered to the other driver to exchange our insurance information in a safer place. How stupid was that!!! Do you know what happened? Yep, she just drove away and I couldn’t follow her because of enormous amount of car around me.
