I took a Lyft ride twice in the same night (to a bar about five miles away - and then back home). BOTH of them were also Uber drivers and had the little "U" in their side window......but NO Lyft trade dress. LOL!
They both were working both 'sides' of the coin, but not at the same time (of course). Each had only gone on four or five rides, so they did not have any way to compare Lyft with driving for Uber yet.
When I told him I was also an Uber driver, he asked when I last had a fare. Been almost a month now - and I am going to do some driving this upcoming weekend just to keep the platform 'alive'. Uber is almost like a hobby now instead of a chance to make extra cash.
