Ahhh, this is along the lines of something I thought of years ago, called the; IP-PHAT unit. ( Intelligent Personal Public House Automated Transport )
A car that I can drive to the pub in, on a Friday night, park up and enjoy my beers with out having to worry about how much I'm drinking or having to keep an eye on the time for the last train or bus or even SHMBO. Then when ready to go home, just sit in the passenger seat and push the home button and let the internet do the rest.
This idea was penned on a bar mat under the influence of toooooo many beers
and by the time it comes, which at some time it probably will, I will have been long since in me coffin
