Looks like I have had a Lyft account for 5.5 years... and never used it. I did use Uber maybe a dozen times over the same period (primarily because I also use it for UberEats to use the $15 Amex credit ... and generally have a few extra bucks from discounted Uber giftcards in my account). So... not expecting to get rich on this new offer. But I linked the accounts.
