I won’t hit 30 rides so…? What happens?

Thanks in advance for any information. I made the mistake of renting a Chevy bolt from Hertz to drive Uber and I got it last Monday. An emergency came up and I had to go out of town and didn’t get back until yesterday morning. To make a long story short I’ve only done 10 rides and I can add to that today before my week is up tomorrow but I know I won’t hit 30 I might even just leave it at 10.

I’m shocked at how little charging stations there are around this area and even the one that’s closest to me is gonna take several hours just to get it Charged up enough to do another 10 rides.

Can I just return it on time tomorrow and start over with a gas or hybrid car or will I have to pay a penalty?

Again thanks for any information
