Uber and Lyft are offering fuel surcharges and cash back offers for workers. Is it enough?

For many gig workers, their vehicles are how they make a living. And as independent contractors, they're solely responsible for keeping them clean, running and full of gas. In recent weeks, the latter part has gotten much more burdensome.

In response to soaring gas prices, Uber (UBER) and Lyft (LYFT) recently announced they'll start tacking on temporary fuel surcharges to rides. Uber, beginning Wednesday, is charging customers an extra $0.45 or $0.55 per ride and $0.35 or $0.45 on delivery orders. Lyft will add a $0.55 to each ride starting next week. Both companies said the fees will go straight to drivers.
