We used to communicate by email, which hasn't changed and is still valid. They have reems of personal data about me including my bank routing number, my phone number, my driver's license, etc... I got one email from Lyft offering a $200 bonus for 10 rides in a day, but nothing from Uber. $200 for 10 rides is not exactly incentive to get off my retired butt and do some driving again. I'm now looking at python freelancing for a little extra cash.
Edit: I logged into my Uber driver app. Nothing beyond the usual promos (bonuses for driving in San Francisco.) Nothing like, "Hey, we noticed you haven't been driving. We want you back! How can we help you get started again?"
