Just read this on BBC News app and thought you would be interested. Bear in mind is a bit lengthy and is British, referring to European standards, BUT the results are the same wherever you might be. http://bbc.in/2yrTnyW I'm really struggling with Prius Chat today and can only hope this gets through all the hoops.
excellent article! after spending the week end in new york city, i can well relate to this. unfortunately, something like this would be all too confusing for government officials sort out, especially with the strong arm of lobbyists at their sides. i think the comments about electric vehicles is a bit of a straw man, because all cars throw up dust and have tyre wear on top of their tailpipe emissions. and ev's have much less brake wear than gassers.
