For a lot of people it is one less thing to work into their routine. For other people it is hassle. Round where I live no houses have driveways or garages, so the only electric vehicles I have been seriously researching have been motorbikes that can fit through the front door and as much as I think electric cars are the future of much of transport, the charging cable problem hasn't yet been seriously addressed for high density urban use yet.
edit - Or fold-up cars. One that can fit in a lift.
In London there are 1300 public charge points so far. I have seen people just running charge cables out of their front window to the kerbside. Garages are not very common in centralish areas. So I think bringing it indoors is pretty extreme.
