I know but maybe she didn't take notice to it when she first got into the car. And the windshield was broken and now from my knowledge police cars use Windows, pending on the year

The man that Ana was with was very thorough and wouldn't let that slip by unnoticed. He would have made sure nothing was in the backseat when he first got the vehicle and would have kept the vehicle secure until his passing. Ana did nothing but sit inside the vehicle since the man's passing. So it is unlikely, however, I was going to point out in my next post that the beep of the horn caused a few shambling zombies to roll out of the bushes and slap away at the car. Perhaps that could be your extras?
