GM riles Californian electric car world (again) over AB475 "charger sharing" ban
California has had public charging stations since 1996. Relevant state legislation makes no provision for plug in hybrids, which didn't exist at the time.
Should a plug in Prius or Chevrolet Volt be allowed to use such a charging station & it's associated parking spot? Should the owner ensure that the EV is moved after it is finished charging? Or is it OK to continue to use the parking spot after the battery is charged?
The item below discusses some issues which will be of importance in other jurisdictions in years to come.

Mazda's Skyactiv-G 1.3 gets 70mpg (US), No hybrid tech needed
update 15Aug2011
All of these fuel economy figures are better than a Prius hybrid!
Use of a 14:1 compression ratio & a continuously variable transmission (CVT) is suggestive of an Atkinson cycle internal combustion engine which is one of the major efficiency provisions in hybrids (Prius, Civic, Insight& Volt). In those vehicles, an electric motor (combined with a CVT) is used to provide the low speed torque which Atkinson cycle lacks.

Fuel consumption figures used in the above article are a little confusing. Miles per gallon numbers are based on the US gallon, which is of course, hardly unusual. However, use of kilometers per litre, is in HHG2Tech's experience, unique. Just for the record:
30 kilometers per liter = 70.57mpg (US) = 84.76mpg (UK) = 3.33 l/100km
56mpg (US) = 67.26mpg (UK) = 4.20 l/100km
All figures rounded to 2 decimal places.
And 56mpg (US) = 23.80 km/l if anybody cares.
