Failing fast and cheaply (e.g. below $5 mln) is good and essential for innovation. You can still learn a lot, test some concept and next time be more successful.
E.g. Cost of 1000 dead YC style startups is likely still very positive, while BetterPlace from $850mln to zero is just a drag for the economy. Most likely those $850mln could be deployed more efficiently.
For example, Better place. Sure they we're wasteful.
But if they took the same idea, focused in the taxi market in a certain city(for charger density, battery use density, and mayor support) , and maybe worked creatively , instead of needing a new car, maybe using a pickup truck and putting the removable batteries in the back, and deciding on a more sane charging cost - maybe this could have worked.
But $5mln sounds low for that.
Shows that if you are on the YC rocketship, you either go big and get acquired or die out trying.

I'd guess that pretty much every batch has startups that implode very quickly due to disagreements within the team. The company is dissolved and the founders end up disliking each other. This is pretty bad but nobody has heard of these companies and it's clear the team was just bad. A decent team is able to persevere for some time.
The more interesting examples are companies that had traction, were growing, raised lots of money, but some aspect of the business didn't work out or they got beaten by competitors, and ended up shutting down. Homejoy is one example. The problem is many other companies like this end up getting acquired for some small amount of money instead of shutting down, making it plausible to deny they failed badly.
On the surface I understand why the idea was thought to be a good one. But getting sued by SFO because they didn't have the proper licensing agreements pretty much killed that company. There may have been more, but I remember that particularly.
There was also the personal lingering questions about insurance, questionable whether the customers would be good (one damage incident spoils the well), etc.

These days it seems like Uber and Lyft have really captured the airport pickup/dropoff market. It looks like Turo (formerly RelayRides) is still active in the P2P space though, and they've raised $172M.
