And you know these idiots will be happy to sue even if it's their own fault. If it has to move as slow as garage door then it doesn't serve its purpose.
Sounds interesting on paper, but I question its practicality.

With the internet of things and basically everything having an unnecessary connection to the internet, like fridges, washing machines, dildos that have cameras on them, even car washes, I can honestly see someone hacking into this and creating some havoc with deadly consequences, not to mention what would happen in the event of a power failure and some people just so happen to be underneath it.
