[Star Wars] Why was C3PO driving the speeder?

When R2 runs away and they're looking for him in the speeder, Luke can be heard to tell C3PO to "hit the accelerator". Why is Luke letting this untested (and at this point, not exactly trustworthy) droid drive him around?

Droids are used as capable pilots across the galaxy, and there's not a lot to crash into in the Tatooine desert for the most part.

C-3PO hadn't shown any defects, so Luke made a judgement call that he'd rather focus his attention on locating R2-D2 himself than on driving.
