Support for electric cars has certainly greatly improved with new chargers being installed in various locations, especially in the last few years. However, I don't see electric cars going mainstream unless the charging time is drastically reduced. I seldom see electric cars in my area at charging stations (maybe one every few days?), so I hardly think it would be worthwhile to specifically cater attractions to electric car drivers.
By the time the charging times are reduced and if they do start becoming mainstream, I think it would be a moot point since there would probably only be a limited span of time for when that sweet spot happens (where charging time goes down and ownership goes up) to make a business based on that limited opportunity where there are enough drivers waiting at a station for a significant amount of time.
