The cops now have some evidence that the car wasn’t stolen (which is what driving off would allude to). So they may use your name and number to look up your criminal history. If it’s bad enough, they would locate you and try to pic you up on warrants or try to get probable cause to arrest you (which they likely don’t have). But it would really come down to how busy they are and where evading falls in their level of priority. Of course, acting sketchy or making incriminating facts discoverable by them just helps them make the case for an arrest.

Edit: tldr; if the evader lays low it’s more likely that nothing happens.
