Launch your product, or don't. But I'm not clamoring for an "invite".
When it's actually for-real, then it's easy to compare the price/service ratio.
Marketing critique aside if the idea has legs, people may be interested (perhaps with a better message). That's my takeaway. Practically, at the right price, I might use a service like that.
1. Don't have to drive 2. I can be somewhat assured of quality (and not have to rent a limo & driver for myself).
For lyft, on the other hand... not so sure.
Don't woo me with "the orangest chairs in America" and film it in black and white.
Generally, I look at language like this as how they want to position the product in the marketplace; I think there is still some value in knowing this, although you cannot trust it until they offer something more tangible.
Also, "affordable" is a weasel word. "Most affordable" may not mean "lowest price."
