The point wasn't to avoid people (I consider that a downside actually), it was to save having to have a vehicle come pick you up twice a day or generally having to drive around without a fare. It'd be your own personal vehicle and it'd have to be as small and light as possible for this exact reason - I had imagined golf cart sized. The vehicle would only need a minimal battery because it only has to take you from the station to work and home to the station (and could charge on the train and at work). You're right though, I dunno if the economics would ever work out. With the disclaimer that this was just a fantasy and probably shouldn't be taken too seriously.
