For the most part speed doesn't kill compared to crossing into the other lane and hitting someone head on. Not to mention this really hinders all the new cars with their line following/lane changing tech.
The point is there are use cases outside of what most people here complaining about people with Nests have. Not saying its the only solution, or even the best. Just saying that the overall hate in this thread towards such a device is short sighted.
I see a lot of hate for the Nest. However they are very useful for people who have a vacation get away. Nests are pretty useful for these homes and I know I'd be ticked if I showed up at my little mountain getaway in Vermont and had busted pipes.
If I wanted to vote for everything I'd become a politician. The idea is to elect people you think are like minded and want the job, and let them run the show. There is more to life than politics. I'm tired of being bombarded 24/7 with politics.
