Business Ideas: A 2 person mobile home

alright, this picture is a little too "futuristically-dark" for me, but it holds the essence of what could possibly be a best seller.
we've been hearing about green cars, electric cars, etc, but we haven't really heard about the kind of applications this could be used for!
my idea (which i'm almost certain isn't original) is a smaller version of the mobile home, and maybe a tricked-out humvee, with a queen sized bed in the back, a tv, and a tabletop for a laptop. in singapore, we have a wireless modem attachment thingy that will allow us to get unlimited internet access for less than $30 a month. i'd say this is built for us!
a sunroof and a pocket fan would be extremely important as well. or perhaps an air-filter to replace the sunroof.
and this car must be electric! speed will probably never be an issue, as a mobile home isn't meant to win any street races. but if someone were to live inside it, it has to be at least cost-effective.
and why a small car instead of a real mobile home? well, cos we're space deficient in singapore. and it'll be hell trying to find a parking space for a bus (which is exactly what a mobile home is like).
applications: working too late in the office. too tired to drive back. too drunk to sleep at home. got kicked out of ur bed by ur wife. and well, other stuff.
is anyone gonna build something like this?
