OnStar by GM has many of these features (app, location, unlock, customer service representative can unlock etc.). I don't think there is a recorded hijack/hack there too.
It's not that these features exists which is the problem. It's that Tesla has implemented it's security poorly, potentially exposing these features to hackers.
Calling from the registered phone number and verifying address is all you need to get OnStar to unlock your car (I am not sure if its still the case now, but it was the case two years ago).
Same thing for username and password. That's all you need to log into their app. Not sure about failed attempts, but there are no other authentication methods.
I will add to that - use FB ads just for retargeting, because it is relatively cheaper, and you know these are interested users.
There is a cool YC startup https://www.perfectaudience.com/ that does just that.
You cannot afford to worry about patents now. Just avoid them altogether.
Also, just don't look anything up, or send emails to your co-founder / or anyone else specifying any patents. Because if you will get sued, you will have to disclose those emails in discovery. And violating a patent knowingly is a whole different story than violating it unknowingly.
By default, these messages will not go to their inbox. It will go to the "other" box (aka spam :) so unless the user will go in and check it manually they will never see it (no notifications etc.)
Awesome!! Feature suggestion: keyword search on top of it. e.g. I can search "call" to get all the domains that has "call" in them in order of pronounceability.
Probably Detroit or its peripheral cities (there are some nice ones, Birmingham, Royal Oak and more). Dan Gilbert (Quicken Loans) is trying to revive downtown and investing in new startups.
Also it's only 45min away from Ann Arbor which is an awesome city.
You can rent an apartment for the cost of monthly parking in SF :)
Thats Detroit proper (do not move to downtown Detroit or Flint :) but the cities around Detroit are good, and I don't know much about the schools there but it's worth looking into.
Oakland County has some of the richest cities in the US (a lot of old money) so you can easily find a nice city around Detroit that will be cheap and still very protected.
I've lived in extremely high crime areas before. One study of my neighborhood predicted I had a good chance to be dead within 5-10 years because of crime.
The truth is that unless you're part of the drug trade or other nefarious dealings, you're usually pretty safe. I can't speak for Detroit, but I'm always suspect of these stats.
Rochester/Birmingham and other cities have some of the best schools in the state. The northern burbs are on par with any good suburban area in the country.
