It’s weird, I’ve been using Lyft as my only ride-sharing service for almost a year, but still catch myself saying “I’ll Uber over there in a bit” all the time. It’s definitely because saying “I’ll get a Lyft” is indistinguishable from “I’ll get a lift” and I was to disambiguate that I’m talking about a ride-sharing service, but I wonder how many other people do this and if (in several years at least) their trademark is in danger.
