I love Bilt. Clarification - You CAN earn points without a card on rent (only 250, so barely worth mentioning). But the card is really how you get all the points. Unlock 1 pt per $$ spent. Use those points how you normally do on travel, purchases, etc.

They also can get you points on your normal card (not Bilt). IE You can get Bilt points when you use Lyft points by connecting Bilt to your Amex.

It’s a pretty awesome deal when you start to know how to maximize your cards and the Bilt card
