Not sure how this ended up on hackernews, but do yourself a favor, and at least once, attend a track day, drivers education day, or find some way to get your car(yes your car, it can be really any car) on a race track. If you catch the itch, Lemons is fun, but check out Lucky Dog!
Cool concept! I do have a concern about the healthcare aspects of the product as advertised. Do you provide a signed BAA for healthcare organizations? Without one, all the healthcare use cases listed on the site are basically a non-starter. Having said that, if you are using AWS as described, you already have a BAA with them, and providing one to clients should not be a huge deal.
