What infrastructure? all you need is an outdoor 220 or 240 V outlet(110V in US). Most car ports and garages already have them, if not easy to install.
Your 20km drive to work( 40km round trip) can be handled by all EV's, and most PHEV can at least do the one-way trip in electric mode. Sounds like you could be saving a lot using an electric vehicle if petrol goes to higher than $3/L. In the meantime you can do what I did in the US in the 1070's car pool with 2 or 3 others, until your back-ordered EV arrives, car pooling is the fastest conservation measure if mass transit is not available.

The other change we need to put in place is timed metering. The system would struggle to handle the load peak at 6.00pm if we had a significant proportion of EVs.
Ideally recharging would occur during the day where it could be matched by solar generation, but the infrastructure associated with both the demand and supply would take many years to put in place. The immediate solution is timed metering to houses and payment of off peak rates for charging at night. This is relatively simple to impliment and could be rolled out progressively with the uptake of EVs.
