I currently drive for Lyft and Uber. I've found having both of them to be a nice option--sometimes one is offering more Primetime/Surge pricing, other times it's just nice to have to options when things are slow. And who doesn't want an easy, quick $1,000!
Of course if you don't like driving for Uber you can just go back to Lyft after that great bonus!
Email me if you have more questions, I'm happy to help! Thanks, Ryan.
