I kinda like it, it's got the word "Car" in it. "I drove a Carve to get here" sounds more natural than "I took an Uber"
Believe it or not, my co-founder and I actually ended up flipping a coin to decide on the name! I wanted DrivesUs (mostly because the domain was available) but now I feel like Carve sounds a little more sleek and pithy.
DrivesUs would be a problem for me, because I'd keep forgetting whether it was DriveUs or DrivesUs
