Look to Norway for incentives for buying all-electric cars: We have 0%VAT, free public parking, free passing in toll-roads and ferries, a symbolic yearly registration fee (400 NOK as opposed to ~3500 NOK for a diesel car), and electric cars are allowed to use the bus lanes. (I usually throw in that the limit before being charged for DUI is higher, but that works better when just talking to someone than when typing it. ;-) )
Charging stations (both trickle charging and fast charging) are being built all over the place, and are free to use. With the "triplets" (Mitsubishi/Citroen/Peugeot) and the Nissan Leaf we're really seeing a boost in electric cars being sold. I now own two myself, letting my family be all-electric on a daily basis. For now we're keeping the VW van for the longer trips, but as soon as there are fast-chargers between where we live and the in-laws, the VW goes.
